Darkest Dungeon (the first)
It’s fun, but particularly punishing now that most available missions are at the hardest difficulty.
Not too sure how long I’ll keep banging my head on certain bosses though.

Dave the Diver
It was interesting, refreshing even, but I don’t see myself playing too much past the the main story.

Shattered Pixel Dungeon
I’m playing on my phone, an everlasting classic in my rotation.
I do have it on Steam, but I mostly play on my phone, I’m just used to using the Wacom pen (Samsung Note) for this game.
A mouse would be fine too, but I usually play this on the couch and not at my desk.
