Ah Farcry 2, been a long time since I've seen a game with that much potential turn out to be right shit. The combat was solid, vehicles horrifically boring to drive (but again solid enough to get by on) and guns + healing system were pretty and fresh. But all of this was pissed away in a tide of shitty Ai and appalling plot / missions.
Had the game for months now and still not completed it, got around half way through the second area before something more interesting (see: anything) came out and went to play that instead.
Surprised Yahtzee didn't mention the absolutely retarded way in which when you drive through a camp all the happy little inhabitants will jump on their land-rovers, pull up behind you (even if you're driving at full speed) and start gently poking your car, excellent ai right there.
