I think I gave a thumbs up for this some time back but today Steam put it on sale for a sawbuck (US) over the week-end. I just had to pass along the happy news.

Be aware that there is an official patch and some modding community out there so anyone remotely interested should check the scuttlebutt on the net regarding this unpolished-at-release gem. Current Metacritic score is 80 and I think that is lower than it should be because of the inherent issues with the game because of developer Troika going under before they could fix it with patches. The final official patch made it playable and the unofficial patch is supposed to make it pretty smooth.
