I almost bought a lot of games, but I limited myself to:
Cook, Serve, Delicious!
Nihilumbra
Ducktales
Papers, Please
Mark of the Ninja DLC
Legend of Dungeon
Universe Sandbox
La Mulana
Gone Home (Humble Store)
Guacamelee Gold Edition (Humble Store)
Gunpoint (Humble Store)
Castle of Illusion (Amazon)
Brothers: a Tale of Two Sons (Amazon)
Call of Juarez Gunslinger (Amazon)
I even had time to play some of them, like Ducktales, Gone Home, Cook Serve Delicious and Papers Please.
Cook, Serve, Delicious! totally hooked me.
