I guess I'm in the minority here, but I found the game boring. I own the PS3 version. Maybe I need to download some mods, but I'm not sure that would help. I feel like the online matches are way too frantic. Most of the weapons are too powerful. I like when people set up the game as one shot, one kill with unlimited ammo, though (with the laser shooting gun thingy). I guess I'm all over the place here :)
Just not my cup of tea, I guess. The game is definitely beautiful, though. It makes me excited for future Unreal Engine projects.
My End of 2008 Hardware Predictions (console only):
Wii : 50 million
360: 28 million
PS3: 24 million
These predictions were made on January 3rd and won't be revised
