Prison Architect.
It may be in alpha, but it's one of the most feature-complete (for each monthly release) alphas out there, it's by Introversion (Darwinia/Uplink/DEFCON), and it's basically Theme Hospital in a Prison.
also Don't Starve (if you haven't already played it), perhaps if only because once it gets the multiplayer expansion the price rises to $19.99, not that it ain't worth it. I love Don't Starve.
Teleglitch is also interesting, but you might want to do some research, it reviewed well at Destructoid, for what it's worth. Rougelike top-down shooty type thing.
And all the Tex Murphy games just went up on Steam, seemingly (of course you *can* get them DRM free, but you said Steam, so...). They look interesting.
