The Pros & Cons of the Halos

OP CRIMSONxSERAPH

The point of this topic is to give feedback to 343i on all the previous (FPS) Halo games. This is to allow them to more properly understand the strengths and weaknesses of all past FPS Halo titles, so that they can more effectively provide what we, the players, desire for Halo 6. Constructive criticism will provide both the strong and weak points in a concise manner.
So, in a format roughly as I've given below, lay out each FPS Halo game, with divisions of Campaign and Multiplayer, and then provide 3 (no more, no less) of both pros and cons. This will help you stay objective, as even if it's a game you love, you'll be forced to narrow down your favorites to 3, and honestly consider the drawbacks of the game. Likewise, you'll be forced to narrow down your 3 least favorite aspects of a game you don't like, as well as honestly consider the positive aspects of the game.
The only FPS game where exceptions are fine is Multiplayer for Halo 3: ODST, as its MP was a single gametype (Firefight). You can add 3 pros and cons for Firefight if you'd like, but don't so isn't necessary.
Please avoid listing the same points in multiple games; instead, list the game with the first appearance of the pro/con.
Please avoid listing main pros/cons in a generic manner, such as saying "It's horrible" or "it isn't [other game]". You can list your opinions, but give specificity.
Please refrain from discussing a game's music. We all understand the direct emotional connection the music can have to the gameplay, but we need to stay focused on the task of the gameplay itself.
Lastly, please keep in mind that all of these are opinions. The point of this topic isn't to debate opinions. This is just a stage by which to present your own opinion in a constructive manner. Keep things positive.

Without further ado, my Pros and Cons list:

HALO: COMBAT EVOLVED

    • Lackluster boss battle
Multiplayer
Pros

    • Weapons & vehicles available in campaign not available in MP
HALO 2
Campaign
Pros
    • View into human life (Earth missions, UNSC compatriots, etc.)

    • Customized canonical character
    • Greater in-depth understanding of government organizations
    • Emotional/personal story utilized for greater narrative

HALO 5: GUARDIANS
Campaign
Pros
    • Utilizing important characters of lore
    • Glimpse into human (and Sangheili) politics (outer colonies, civil wars, etc)
    • Scale of damage and destruction (and threat)
Cons
    • Playing as Locke (character fine, but control should only/mostly be for Chief)
    • Story, large in scope, felt flat/uninspired
    • Worlds were uninteresting to be on
Multiplayer

    • Scale of the sandbox
Cons
    • Warzone introduces pay-to-win through REQ system
    • Disorganization of all unlocked REQs and customizations

I'm gonna take a different approach:

Pros of all Halos

  • story-driven game with character-driven story
  • visually arresting
  • music (O'Donnell and Jinnouchi)
  • immersion
Cons of all Halos

  • too gamey in the sense of steep learning curves and wide skill gaps
  • ridiculously over-focused on team-based gameplay
  • ranking systems that never quite seem to please everyone
  • matchmaking systems that never quite seem to please everyone
  • legit yet shady phenomena (like "lag" or "heavy aim" or "exploit ___") that can't quite be explained and therefore cannot quite be understood and yet which undermine game integrity up to the point of almost but not quite crippling it
I don't care too much for multiplayer so here is my assessment of the campaigns...

HALO: COMBAT EVOLVED
Campaign
Pros
  • Open world environments
Cons
    • Jumping/driving mechanics are extremely poor
    • Higher difficulties are a little too difficult
HALO 2
Campaign
Pros
    • Interesting new characters (Miranda Keyes, Tartarus, the Prophets, etc.)
    • Playing as the Arbiter ;-)
    • Fighting through the civil war in High Charity
    • Diverse, semi-open world environments
Cons
    • Jackal snipers
    • Legendary co op
    • Unforgiving LASO (invisible enemies with increased health and awareness is ridiculous...)
    • Undying brutes (too strong)
HALO 3
Campaign
Pros
    • Impressive introductory mission
    • Best open world environments up to this point (the Ark, the Covenant)
    • Fighting two scarabs at once
    • The story as a whole
    • Equipment and gravity hammer
Cons
    • Cortana's transmissions
    • Assets for human environments are frequently reused
    • Some missions are too short (Floodgate)
    • Flood look less creepy; the transforming ones are annoying
HALO 3: ODST
Campaign
Pros
    • Stealth encouraged; mindless running around, not so much
    • Memorable environments (Uplift Reserve, NMPD HQ, Kikowani Station, Data Hive)
    • Night vision
Cons
    • Confusing to navigate
    • Almost everything looks the same (buildings, streets, cars)
    • The pistol is just about useless
HALO: REACH
Campaign
Pros
    • Learning more about Reach
    • Fighting on a Corvette
    • Brutes are most fun to fight
Cons
    • Unnecessary and somewhat annoying armor abilities
    • Brutes wear eye shadow now?
HALO 4
Campaign
Pros
    • Learning more about the forerunners
    • Impressive forerunner environments (Forerunner)
Cons
    • Art style resembles little of previous games and Halo, in general
    • Enemies are predictable
    • Tactics against Prometheans are limited
    • Teleporting, respawning knights
    • Forerunner character designs
    • Exploration not encouraged (I can no longer jump happily to my death, if I wish...oh, and kill timers)
    • Covenant don't quite look the same
HALO 5: GUARDIANS
Campaign
Pros
    • Fighting alongside Blue Team
    • Gorgeous and complex environments (Blue Team, Swords of Sanghelios, Enemy Lines)
    • The Kraken and Phaetons
    • Improved vehicle and weapon designs
    • Opening action sequence (say what you will...)
    • Knights look more formidable
Cons
    • Art style is still too different
    • Some environments aren't so pretty (Genesis, Evacuation)
    • The story is slow and uneventful
    • Character development is poor
    • Too many Warden Eternals (the Breaking)
    • Legendary difficulty isn't that difficult

Thanks for the comment, and especially for paying attention to my "guidelines". I wanted to make this as much of a constructive place for our very subjective opinions as possible.

Shameless plug...I think I might do another post just like this one, but aimed at what our biggest hopes for Halo 6 are, in terms of campaign and multiplayer.

I know, I know. But that doesn't stop me from calling it out, or from hoping that some day someone somewhere (preferably at 343) will devise some mind-bending and logic-defying solution.
I din't play Halo CE and Halo 2 until CEA and MCC so I won't include those games. Neither do I include ODST because it was like Halo 3 and dind't have multiplayer.

Shameless plug...I think I might do another post just like this one, but aimed at what our biggest hopes for Halo 6 are, in terms of campaign and multiplayer.
No, please don't do that. There are multiple popular "what we want in Halo 6" threads that are active. Stick to the existing ones rather than making a new one.
NOTE: I'm doing a 2-part to my comment because I have a lot to say. I'll be splitting this into Bungie and 343 games. I'm not going to be bullet-pointing every little pro and con I have with each game, but I'm going to be bulleting quite a lot. "+" are pros and "-" are cons. Here we go...

Bungie Era Halo Games

Halo: Combat Evolved

Campaign

+ Introduced one of the best soundtracks in game history!
+ The characters are all really good (except for guilty spark!)
+ The introduction of the halo world was brilliantly done!
+ The level design is perhaps the best in the franchise. It's open and fun to explore for hidden caches of weapons, powerups, and health packs.
+ The AI respond to your actions in a unique way that no other game prior had been able to accomplish. This isn't as impressive nowadays.
+ Revolutionized FPS storytelling and design
+ Enemy AI is spectacular, and realistic as can be expected for the time
+ The story was excellently done!
+ Sound design is excellent and high quality.
+ The art design is gritty, dark, and mysterious!
+ Voice acting is solid
- 343 Guilty Spark is an annoying character
- The Library level is poorly designed and repetitive
- The pistol can one shot a hunter! Lol!

Multiplayer

+ The map design is mixed. It is either amazing (Blood Glutch, Battle Creak, etc.) or terrible (Chiron TL-34, Boarding Action, etc.)
+ Gameplay is extremely addicting
+ Became the console seller for the xbox one
- The pistol is OP

Halo 2

Campaign

+ The story was fantastic
+ Longest campaign mode in the franchise
+ Voice Acting is great
+ The characters, old and new, are great!

- Falsely Advertised
- Development Cycle was cut before the game could be finished
- Lacks polish and feels incomplete.
- Ended on a cliffhanger that left fans wanting more, but in the wrong way
- Linear level Design
- 343 is... alive?!?!?!
- Texture meshes weren't completed before release and as a result the look of the game suffered in some areas.
- The Gravemind level is terribly design and is nearly unplayable on Legendary difficulty (Starting spawn is broken!)
- 343 boss fight was WAY too easy!
- Elites can 1-hit melee you on any difficulty

Multiplayer

+ The soundtrack was spectacular as usual
+ The ending is a masterpiece!!!!! One of the best in video game history
+ The Art design (We all know the reasons, let's just get on with it)
+ Improved Enemy AI
+ First time we see main characters die! Adds emotional weight to a game most people didn't expect!
+ Introduction/Reintroduction of new weapons/vehicles
+ Has the most polish of any halo game to date!
- Replacement voice actor for Truth is confusing
- The Gravemind's disappearance
- Cortana!!! (The level design was horrible too!)
- The Flood AI was clunky, and didn't always do what it was programed to do

Multiplayer

+ Introduction of equipment was fantastic!!!!
+ Has some of the best maps in the franchise!
+ Each map is unique and expertly crafted
+ Replayability is through the roof!
+ Weapon balance and weapon design is spectacular!
+ Widely considered on of the best Multiplayer experiences of all time
+ Has one of the best ranking systems in video game history! (The 1-50 ranking system)
- Snowbound (I'm cherrypicking here. It's my least favorite map.)

Forge

+ The introduction of forge was groundbreaking for halo
+ File Browser
- The controls made it hard to move objects around without knocking other objects over.
- Couldn't build the canvas of maps like in later games

Halo 3: ODST

Campaign

+ The unique soundtrack was mesmorizing
+ The gameplay was great
+ The story was really well done
+ The graphics are excellent!
+ Art design was fleshed out really well.
+ The noir tone of the game was implemented masterfully!
+ The new characters were great (Aside from Dare, whom was kinda just their for the ride)
+ Adds to Halo 3's campaign in a way that is excellently done!
+ The Halo: CE Health bar makes a return!

- The stealth mechanics didn't really work with the game

Firefight

Halo Reach

- Plasma Repeater is useless!
- Map design isn't very good

Forge

+ Introduction of various forge features including phased and fixed mode
+ Heavily built off of what was sorely needed in Halo 3's forge mode
+ The sense of community outreach from Bungie
+ Forge mode is a forgers paradise!
- A lot of the color grey! You kinda get sick of it after a while
- Forge mode was slightly falsely advertised (Bungie announced that we'd you could go passed the mountains in the backdrop, but when the game released, we couldn't go there)
NOTE: I'm doing a 2-part to my comment because I have a lot to say. I'll be splitting this into Bungie and 343 games. I'm not going to be bullet-pointing every little pro and con I have with each game, but I'm going to be bulleting quite a lot. "+" are pros and "-" are cons. Here we go...

NOTE: I'm doing a 2-part to my comment because I have a lot to say. I'll be splitting this into Bungie and 343 games. I'm not going to be bullet-pointing every little pro and con I have with each game, but I'm going to be bulleting quite a lot. "+" are pros and "-" are cons. Here we go...

+ The level design is perhaps the best in the franchise. It's open and fun to explore for hidden caches of weapons, powerups, and health packs.

- 343 Guilty Spark is an annoying character
- The Library level is poorly designed and repetitive

- Texture meshes weren't completed before release and as a result the look of the game suffered in some areas.
