Everspace is very cool - it's a rouge like where you upgrade your ship as you progress with very unique skills and different branches.I'm also in love with Cosmoteer - 2D game where you can build, rebuild, salvage enemy ships, eventually create a small fleet and experiment a lot with different designs.
Brothers: A Tale of Two Sons - pretty cool as you can play on 1 controller.Star Wars Battlefront 2 (OG) - have awesome memories with it.Earth Defence Force 4 or 5 - over the top bug extermination and built in split screen even on PC.Last thing I can recommend is Saints Row 2, 3 and 4 (especially 3) - but you need something like Nucleus to play on the same device.
I'm sorry that you also have to deal with it. Tracking helps to hold a routine and at least for me to look back and see trends - even lows eventually pass so this current one also eventually will.
CosmoteerIt's a 2D space sim where you build spaceships, manage subsystems, break up pirate ships to add parts to yours (even mid battle), with absolute freedom to do whatever and mechanics that encourage experimentation. Man, I don't remember when a game pulled me in so bad.
