I'm all for gamers getting hold of collectibles for games they like. Sure, it's geeky as hell and maybe you don't get to display them when polite company comes over -- Morrigan is one such figure at my house -- and right now there are plenty of deals out there. Take for instance Gaming Heads' huge Tank figure (from the Left 4 Dead games).
It's on sale right now through Sideshow Collectibles and worth serious consideration for fans. It's kind of a macabre figure to have on display and I think I'd rather have a Survivor diorama, but still you get what you pay for with figures like this.
