I've been burning through some Gamepass offerings that I've passed over.

The Wolf Among Us is a fun Telltale game.

Superliminal is a good mindfuck puzzle game. There were a few times that it took me a while to find the key to the puzzle, but I never felt "stumped" throughout the game.

and I'm a few hours into Monster Sanctuary which is essentially Pokemon in a classic Metroid map. Having fun so far and planning on sticking with it for a while.
