Well, I'm extremely disappointed. I wasn't expecting much from the story; I got less. What I've experienced so far is an arcade game with high-end graphics. Repetitive gameplay, too - how many mercenaries are there, really? The "intelligent" AI disappoints, and respawn rates are ridiculous. The weapon selection is nice, but having to hunt down diamonds to pay for them limits the number you'll actually wind up using. Sure, you may want to pick up X gun for fun, see what it does. But chances are you'll miss more than you see.
Then, there's the driving. Not only does it have that dumbed down console feel to it, you have to do it so much. Missions that only take about 2 minutes usually take 8 or 10 to reach. The fast travel system only has five transit points for the first third of the game, and a large amount of mission objectives are placed about halfway between two of them, negating their usefulness.
The music is repetitive and boring, as well. Sound effects could've been so much better... the oft-touted fire of the game sounds bland, and weapon effects are cookie cutter. Overall, the game is cheaply entertaining for a while, but certainly lacking overall. Maybe I've just been spoiled with deep stories and excellent gameplay from games like Mass Effect and Fallout 3 this past year; or maybe, Far Cry 2 just isn't that great.
Yeah, I'll go with the latter. 5.5/10
