Space Marine (could be in the HTHQB soon however)
Games I don't recommend:
Deadlight: Nice concept, but bad technical implementation and somewhat clunky controls. Maybe for 5$, but not more.
And how on Earth is Port Royale 3 a gamepad game !?!?!?!?!?!
And in a typical Stem move: Their "controller fully supported" tag doesn't even have a picture yet ...
