stardew? cause, farming digital crops for currency feels good? just don't make iridium sprinklers, once i automated mt farm My interest in it fell a lot.
Binding of Isaac. Very difficult, easily 500 hours or more to finish all endings for all characters. Plus, there is a daily challenge with leaderboards, multiple game modes, and new content still being created.
I still love steamworld dig! I enjoyed stardew but when I play I get sucked in and before I know 5 hours have passed by and I wasted my whole day LOL. Snake pass was fun if you are up for a challenging controls!
If you really like 3rd party indie titles (which I don't care for) you might want to try something like Shovel Knight. Heard decen things about the series.
