I'm hoping Infinite keeps this close because a lot of reasoning behind H2 and H3 being limited and labelled as "classic" was merely an engine limitation on what could be done.
It's well known that Halo 2 had a sprint animation that was cut from the final game (allegedly due to pacing issues). We also know that Halo CE had a working jetpack that was cut (see here). Unless you can find me a specific quote from a Bungie designer explicitly saying that advanced movement was not possible in classic Halo games because of engine limitations, I'm going to have to say that claim is nonsense. There is nothing about any of the advanced movement mechanics that fundamentally is limited by engine performance. They're just animations. Maybe with older animation techniques they're not going to look as polished, but that goes for any other animation, and it's not a reason a developer would drop a mechanic.
The classic Halo games are as they are because the designers made the call to not include some mechanics. But even ignoring that, "the games are the way the are only because the developers didn't do certain things" misses the point. Sure, of course they are, but that doesn't mean they aren't good design. There is this weird idea among some gamers that just because one game did some cool thing, every other game should also do that same thing. That just because a thing can be done, it should be done, and there's no room for games with unique and simple designs. Every game in a genre must succumb to the same trends. That's boring.
I may not like it when people think their personal preferences dictate what Halo needs to be popular, but you shouldn't mistake that for supporting the the current direction.
Which is exactly why I've always supported Halo with each title. Yes, there's little nuances that bother players, but I learn to adapt. Halo has always been my most play series for FPS by long and far......I don't play any other shooters religiously like I do this.
I strongly agree with you on the fact that all the games are great in their own rights, and that each iteration copying the last would be boring. I like innovation. I like changes. I also thought don't like going backwards with mechanics. I can understand equipment from H3 being gone and replaced with AAs in H4 (chronologically) because H4 was War Games simulation. H5 involved different worlds and thus would make sense that equipment isn't found vert often. Factions upgrade weapons, equipment, and utilities even in real life. That's why thrusters making use as abilities in H5 make sense to me. Yeah, a lot of people don't like it, but it doesn't mean it doesn't work or was thought out correctly.
I also meant pointing out the generational games from each other. CE/2 on OG Xbox had limitations based on console that it couldn't do or do nearly as well as 3, 4, or Reach. Each game was built better than the last as the console architecture was used better. Same with going from 360 to X1. There's things H5 can do that I'm sure the 360 versions of Halo can't do nearly as well or at all either. Sure, they could probably have done something to do that now, but back then these options we have available to us weren't feasible, and honestly, would've just made the games more cumbersome.
Each game does its own thing but does it well. I just don't care for the people that say we need barebones movement and gameplay. That's what CE and 2 did. Everything after is a new experience and people are just too damn stubborn and want to live in the 2/3 era. That's what MCC is for. Let's let Infinite be its own thing and not throw everything out the window simply because of nostalgia.
