Though I haven't played it in a while, I'd like to comment that Longbow games seems to have excellent support for a small team of developers. They're beta testing their patches (which has actually made me hesitant to try it, I'd rather wait for the full patch) and if you post a problem on their forum they'll try their best to fix it. They've made repeated offers to people having problems to take the player's savegames and try and assess and even fix the problem from there.

That kind of support, coupled with the game's potential, makes it a pretty good buy at $15 USD. Obviously check out the demo first.
