"OMG these graphics are amazing!!!" "There's some issues with them here and there." "Dude, graphics don't matter, it's about gameplay."
I know that your opinion on that matter can be and probably is different but Reach was IMO really good looking game,especially for a game with bigger scope than most other console shooters and it looks like Halo 4 is even better looking game.
So I don't think that some low res textures(maybe due to lack of AF) which you have pointed earlier in the thread or some aliasing will be so destructive for overall look of a game.
Especially now when game runs in 720p with better AA solution than previous Halo games,with higher quality assets,nice art and all other improvements.
There are some trade-offs,like always but in my opinion they are done in right places because IMO Halo 4 (from what we've seen
) is better looking game than Reach and if this is a point so I don't see a reason to not be hyped.
