PLAYERUNKNOWN'S BATTLEGROUNDS (PUBG) is steams current golden child in terms of games. Unfortunately I do not recommend PUBG as the developers spend more time changing sound effects than fixing bugs.

Hero Siege: A diablo 3/Path of exile meets pixel art-esque game. A game you can just pick up and play at any time. Hero siege is a game for those of you who want a grindy game that can run easily.
