I'd have to agree with the Gamespot review.
Controls are adequate, although playing Billy and dodging everything can get boring. It's a western, EVERYONE should be gunfighting!
My biggest complaint is with performance. I have a new Maingear PC loaded to the gills, even an 8800GTX card. Playing in DX10 was good for the first few episodes and then it's like performance hit a brick wall, to the point of being unplayable. I even lowered the resolution and settings to "better performance" and it still ran horribly slow, and then looked bad too!
I updated my video driver and am in the process of updating my sound card (X-Fi Extreme Gamer) since the sounds were getting wonky too.
Hopefully that will correct things and I can continue playing, and actually the enjoying, the game itself.
Then again, it could be because I have Vista.
