I once used to play games on my computer, and record them for uploading to my PeerTube account. 
But I don't do that anymore. Anyways here's some games I recommend playing.

* Alien Arena
* AssaultCube
* AssaultCube Reloaded
* Cube
* Cube 2: Sauerbraten
* Endless Sky
* GNOME 2048
* Minetest
* OpenArena
* Red Eclipse
* Tesseract (not to be confused with the OCR engine of the same name)
* Xonotic

Updates
* 2022-01-15: Turns out my PeerTube account died, also got back to gaming on spare time, granted I hardly have anything else to do. Also added more games to the list.
