I don't know what you fanbois are talking about, the game looks absolutely amazing. The UI seems to be very well thought out, particularly the grenade guides and the one-button-camo, not to mention absolutely gorgeous, given the way that circle that I suppose denotes Snake's environment, given how that's an actual animated, textured feature, one that manages to not break your emersion while still maintaining a level of game-necessary abstraction.
The game's set-up (the rise of privatized, contracted, militaries for nations to hire) is genius, especially with the middle eastern setting. I'll admit that I didn't think so at first, but it's warmed to me exceedingly fast. The setting is incredibly relevant and, especially for US players, brings up a real subconscious moral delimma over which side to help: the western forces or the out-gunned, non-professional, home-town militia, who also lack the eerily artificial and eerily inhuman automated systems that the PMCs have.
... I actually wish somebody made an exact clone of this game for the Wii. Except with vastly downgraded graphics. Although the graphics help really sky rocket this game into an immersive, near-cinematic experience (which I grudgingly admit seems to succeed here), the gameplay systems that trailer showed aren't dependent at all on graphics, the game seems to have lots of work put solidly in design.
