Just looking though some of my higher playtime games, here’s a few I haven’t seen mentioned: (I think they’re all indie or small studio)

Gunfire Reborn - Roguelike fps with infinite replay.

Troubleshooter Abandoned Children - XCOM style battle system with a really really fun way to customize how your character fight. Story is pretty lame though (I ended up skipping it) and it’s pretty grindy.

Thronefall - Pretty challenging base defence.

The last spell - Turn based base defence with lots of different ways to build your characters.

Ratropolis - Roguelike real-time card strategy base defence. Pretty good, although not well balanced at highest difficulties.
