that was worst conference ever! halo looked pretty decent though

Don't know about PC, but it doesn't look much different from BC2 on xbox. Sure, graphics became cleaner and less jaggy but it still has plenty of blurry textures, overall the graphics is not even near to crysis 2. And the beta still had the same glitches with enviromental destruction, for example I fired about 3-4 rpg rockets in the same wall, and all it got was black stains, apparently some walls in bf are made of tank armor)

I don't understand how games like braid, limbo, world of goo, mass effect, rdr, portal and many others could not be called an art.

Looks like people who say that reach look worse than halo 3, haven't played neither of two. Reach looks way better than h3, much sharper and cleaner, the textures are much more crisp and antialiasing is always welcome. Also lighting is superb, as the special effects. The only complaint is frequent slowdown in performance, which is big shame. Overall Reach looks great, especially for a game with such big levels.
