If you're a physical collector like me, this is a pretty badass deal. All are physical PC releases.
Each one comes with:
An exclusive SteelBook case
Full-color instruction manual
DRM-free game disc
Soundtrack CD
Mini art print with Steam key
But just a chance to own Axiom Verge in this form for $9.99 is more than worth it.
Games for $9.99:
Nuclear Throne
Rogue Legacy
Axiom Verge
Guacamelee! Super Turbo Championship Edition
Punch Club
Jotun: Valhalla Edition
Awesomenauts
Chariot
Stories: The Path of Destinies
Thomas Was Alone

These are apparently very limited run so might be worth something some day. *shrug*
I got Axiom Verge and Rogue Legacy. Love steelbooks.
