Wow, I didn't expect to enter a hate-thread at all. I played the game (pc version) for about an hour today and I came here to post how awesome it was. Granted, one hour isn't enough to have an opinion on the game, but it sure made a good impression on me.
I bought the game expecting a solid, if unspectacular shooter (to play in between epic rpg's). I never really read up on the game and the reviews got me excited (just the scores, didn't read a review).
What I got is something that's exactly up my alley. I love the open world and that I can go anywhere I want. I love the lack of interface and I love hunting for diamonds. In all honesty, if a game gives me a good-looking open world to explore I'm basically sold. From what I've played it's as much an exploration game as it is an fps. I'm willing to forgive a lot of things if a gme gives me these elements. That's why I love STALKER and even liked Clear Sky with its over-abundance of problems.
The only thing I don't like so far is that the world seems a bit empty. It's missing something. I would've loved to see crocodiles and other wildlife all over the place. I wouldn't even mind that you can't interact with them, it just seems dumb not to have wildlife in a game set in Africa. If you shot at them they could just run away or something....anything!
I'm honestly not even interested in the shooter-part of the game based on what I've played, I just want to drive around finding diamonds and shit. The few enemies I did kill went down easily and I can't say it felt particularly satisfying, but it wasn't bad, just adequate.
To me the graphics are pretty spectacular. It runs very smooth with most settings on Ultra High (DX10 really helps in this case, I get 50-55 fps whereas DX9 gives me 30-35 with the same settings.
Anyway, I'm off to play more (though I might play Dead Space as well...too many games), but my first impression is very good indeed.
/edit: I saw a stutter mentioned a few posts above mine. I have that issue as well, it's very slight though, I might try DX9 again, I can't remember seeing the stutter in DX9.
