so what are all the complaints with it? I've seriously considered it and the only specific complaints I've heard is that the graphics aren't very polished and the single player campaign is too short. What else is negative about it?
The graphics aren't cutting edge, there's some things that look nice, but when things look bad... they look bad.
Like in the very first mission, you call in a precision strike to blow off the doors of this huge wall, and the dirt and crap that comes falling down to the ground looks no better than crap you've seen on PS2.
