The game isn't honestly that bad. I bought it for the PC and have played it quite a bit. If I wasn't getting ready for a Ut2003 Tourny I would be playing it more but hey, gotta tune up the skillz.
Alright to the game, Yes the controlls will make you want to rip every key of your keyboard and thow it out the window. This after you've already trashed your monitor because you started banging on it with the keyboard. They suck...horribly. But if you make it through the first 15-20 min of playing the game you get used to them, and they're aren't that bad.
My biggest problem was graphics, no matter what I tried I couldn't get the game to run at a decent speed. So I turned off all the Pixelshader stuff and the game runs great. Yah they're are bugs, some bad ones. But If you look past those as well the game has some great sequences. Good puzzels and an interesting story. I suggest this.
If your patient, and I mean honest to god super duper patient. Then get the game and have fun with it. If not, expect to be yelling and banging things around because man this game needed another 2 years of development. Take it for what its worth.
