You're not supposed to sell these, but for some reason I went through a phase where I thought I was into games. I'm really not--I'm just interested in them in the abstract, so it's a total waste for me to have this account sitting here.
I probably spent several hundreds of dollars on the games here, and I'll sell you the account for $200.
Maybe 40% of the games are PC/Mac, the rest PC-only.
This is worthwhile if you're into PC games but don't currently have a Steam account--all you can do is transfer control of the whole thing, not sell individual games.
PM me for details if you're interested.
