Halo Infinite is pushing way more geometry and everything else.Halo Infinite is pushing a lot more stuff, but some rougher qualities make it feel like it isn't quite a solid generational leap, let alone two.

It really feels like Halo 1 as a remaster/remake. Sticking to that high contrast nostalgic look instead of going more realistic.
