Unexpected purchases

[Slothy]

I just bought KOTOR2 on Steam despite my hating the original on almost every level possible. Why did I do this? Aside from it being $2.50, I bought it solely to try another Obsidian game because New Vegas was awesome. I figure if they could take the mediocre snore fest that was Fallout 3 and make something worth playing out of it's worthless carcass, perhaps they did the same with KOTOR.

Anyone else made any purchases recently that they never expected to make? Even better, were you happy with them after the fact?
