Sea of Stars recently came out if you liked older SNES RPGs. Reminiscent of Chrono Trigger, they even snagged one of the music producers from it. Great story IMO. I got about 45 hours out of it.
Hollow Knight if you like metroidvanias. Played through it 2 or 3 times now. My son and I are excited for the sequel if it ever releases.
Tricky Towers is a family fun Tetris type multi-player game.
Blue Fire, 3D platformer/metroidvania.
Hacknet, OS UI hacking sim.
Crab Champions (early access coded by EDM producer Noisestorm), 3D bullet hell/loot&shoot where you play as you guessed it… a crab. Has an amazing soundtrack.
Darkside Detective, 2D point and click puzzle solver with a hilarious storyline.
