After playing it for about an hour, I can tell it will be rewarding. I maxed out all options, q9550, 280 gtx, and attempted to force AA but I wasn't able too. The gameplay is fun and there are a bunch of skills to choose from. The story seems interesting as this is my first Divinity game. Considering there are more than 100+ hours of gameplay for $40 I am pretty excited. But the graphics are definitely the lacking factor. They are a little weaker than Dragon Age, so not bad but no Crysis.
