If you're sick of massive AAA developers running cash grabs, my suggestion is stop patronizing their games until they get their sh*t together. An excellent alternative if you're looking for a fun FPS game is Battle-Bit Remastered. I personally love this game, and there is a long running joke that the three guys that made this basically shat on the AAA developer world when they released a full featured FPS for $15 that is enjoyable and has 0 micro transactions.
I totally respect what they've done, and I admittedly am not a Call of Duty player, but Roblox graphics are an instant turn off for me and I really don't think the general CoD player base is going to be drawn in by it either. If there was a graphics pack that made it look modern and zero percent like Roblox I might be able to get into it, but not as it is.
I've played some surprisingly good games with untextured polygons.
Star Fox
Race the Sun
Carrier Command 2
That's not to say that you couldn't take the same games and make a flashier version that I wouldn't like more, but I do kind of think that it forces the developers not to use glitz as a crutch. Like, if you're going to make a game with untextured polygons and sell it, you are going to have to have solid gameplay.
Another benefit is that it's easier to revise a game if you haven't committed a lot of expensive assets into particular game design decisions. I think that a long, iterative development process with gameplay revisions is probably a good thing for gameplay.
I kind of wish that one could more-frequently get commercial "HD" DLC for small-budget games, like indie pixel-art games. I think that low-res pixel art is a good way to reduce asset costs, let the player's brain fill in a lot of the detail, but if a game does turn out to be successful and I like it, I'd like to be able to also get a more-detailed version. That way, I'm only paying for assets on games with good gameplay.
I've seen a small handful of games do that, but it's definitely not the norm.
