Yes. I consider Halos 4, 5, Wars 2 and MCC to be great games, not because of what I had recieved with the games, but because of the experiences I have had with them, be it with the campaigns (Yes, I actually like Halo 5's story. Come at me.), multiplayer, customs, among other things.
In my eyes, it is the duty of the player to create their own enjoyment within games with the tools that the developers give to us. If you need an example, look at 5's Forge. The argument that one simply cannot find enjoyment because the game just isn't fun is kinda BS if you ask me (unless you actually tried making it fun like I said, then I see it as valid).
I also don't buy the argument that a game is bad because it does not "feel" like its predecessors. Each game, whether it be a sequel to a previous installment, should offer some new mechanic that changes how it plays compared to the last version. Halo has consistently done this, however until now it has never incited much controversy. 2 introduced Dual Wield, 3 had equipment, ODST had VISR, Reach had Sprint and AAs, 4 extended on what Reach did, 5 had Spartan Abilities and Smart Scope. You get the idea. Understandably, the additional heat may stem from how noticeable each change has been, however I welcome such things. It is imperative that each game mixes up how it plays while also keeping consistency. I know many people have voiced that last part, and I see it as valid. That's something I myself could stand to see improved a bit.
TL;DR, I'm excited for Halo 6, as well as any and all future 343 Halo products. I will be pre-ordering it no matter how it is advertised, and I look forward to the experiences I will make using it. No matter how it turns out, I believe that everyone who plays it should at least attempt to open themselves to whatever it brings us and see past comparisons to games prior. Many of you will either disapprove of my stance, call me out for being an idiot and making a post that has no common sense to it, or just straight-up ignore it. Whatever. I've shared my piece.
