Started off really well, but then some problems start to show...
There's wide open spaces like I said, and to get from point A to C, you have to walk through A, to the exit point, the through B, and then to C. After a few hours this gets very tedious. Let's say you finish a sub-plot and you have to go see someone for your reward, then you look at the huge distance you have to walk and you only have a day to do it, so I'm not even bothering now. The enemies spawn very fast in many areas.... the game is designed to make you rush through areas, if you want to crawl about and snipe people and search bodies and stuff you'll be stuck with never ending spawning enemies and it gets frustrating. You're very limited for how much weight you can carry, which basically means you can carry 2 weapons if you want to carry enough ammo and your weapons deteriorate with use. It's not a huge problem because there's weapons lying around everywhere, but it would be nice if you could upgrade and stick with a certain type of weapon as opposed to grabbing whatever is available. All in all, this could have been fantastic, but as it is it's still pretty good. I don't think anyone will be disappointed playing it, but you won't hold on to it as a classic either.
I finished the game, there's some bugs in this game that need a good patch. The framerates are ridiculous for fast machines like mine and unplayable for slower machines. The sub-mission system is pretty much broken. Missions don't get properly updated as finished or not finished and locations for some are incorrect. This game is a patch or two away from being done.
