I rented it for the PS3 and thought it was fun. The only issue is that all my friends play on 360 so I was just the odd man out....but not many people even used mics. I thought the graphics were extra average. Not bad at all, but after finishing MGS4 I am a little spoiled. The campaign is ok, reminds me of the 3 kings movie. I was only playing on normal and it was pretty easy, the AI sucks though. The humor in the games is a welcomed change.
The multiplayer is my favorite part of the game, but I am used to playing COD4. I dont really do objective based games so I played it like TDM (which pisses people off). It still worked though. I just play the frontline and never guarded the gold. I thought the game speed was good and the vehicles are a nice change. I like being able to pick a spawn point, thats new to me. The patches, tags etc....are also cool.
Other than the graphics I didnt find much to dislike. I am thinking about picking this up on 360.
