The Binding of Isaac Rebirth:
The Binding of Isaac is a Difficult, Randomly Generated, Action, Adventure, Rogue-like that I have enjoyed of the past 6 years now. It’s chalked full of insane content, constantly branching off to new combinations, amazing replay value (Hence you could play this over and over for quite some time), very expansive DLCs, and gives quite the nostalgia feel from games like The Legend of Zelda.
I highly recommend this wonderful dungeon crawler
