I figure I'll want to play Overlord 2 at SOME point.
That's what I really love about steam. They will keep it, patch it up for you. I even bought there Star Wars Jedi and an old 1995 game called Dark Forces came with it's own Dos Box (I could never figure those things out for myself) all I gotta do is click and it works... looks like crap but it works. I'm actually buying more games now then I download.
