In my AP Computer Science class in high school, every now and then our teacher would give us a free day. We would sit around playing Unreal Tournament on the LAN.

At one point the teacher decided he wasn’t comfortable with a game with guns in class.

So…I got everyone to install Cube, the open source first person shooter. Specifically a copy of it where I had removed all of the gun models. So we just ran around punching and bullets would fly from our fists. Or, in the case of the rocket launcher, an exploding sofa would fly from our fists.

I don’t know if I would call it my favorite, but we had a lot of fun with it.

I used to play Tremulous. That was a blast. Very clever game.

More recently, I’m a fan of shapez (shapez.io) for my recommended daily allowance of factory building gaming.

Going back further, I have a soft spot for Ri-li, a nice little game about toy trains with very charming music! It was this which set me on an adventure with the mod tracking scene. A surprising amount of open source games use them, it feels like open source music!

Reminded me also of Alex the Allegator 4, a very original 2D platformer

Battle for Wesnoth - a turn based tactics game in a fantasy setting. It’s also available on Steam and itch.io. Coincidentally, version 1.18.0 was released yesterday.

Go / Baduk.

However the white stones are severely overpowered, and the devs refuse to do a rebalance since around the last 4000 years!
