OpenTTD is a great open source clone of the transport tycoon game. And boohu is an awesome ASCII coffeebreak roguelike.

Thanks for the Veloren recommendation, I liked Cube World, it just didn't work out well.
It's old but I always really liked WARSAW it was/is a quake3 port but with more cartoony outline graphics similar to Borderlands style.
Technically not the whole game, but (Smash Remix)[https://github.com/JSsixtyfour/smashremix] is an open source rom hack of the original Super Smash Bros. for the Nintendo 64. It's been a blast from the past and I'm enjoying the hell out of it.
I also love the fact that a lot of N64 emulators are open source too, like Mupen64 or simple64
0 A.D. and Beyond All Reasons for me ^^
One of my absolute favorite games as a kid was Glest. Turns out it's open source and is now available as MegaGlest!
It takes a lot of inspiration from Warcraft but it has its charm and many of the races are quite unique in how you play them!

I've had a ton of fun in Red Eclipse over the years.
Only one that comes to mind is Lugaru. The creator had this weird legal battle where someone stole the game, ported it to iOS, and the thief claimed because it was open source he was allowed to sell it.
Surprised it's not mentioned here, but Bzflag.
Super fun tank shooter game that doesn't take much to run, and reminds me of a cross between the very old bolo game and Mario kart's battle mode.
classicube is pretty cool, open source Minecraft classic-like game (so, no crafting or survival aspects, limited world sizes)
The only one Ive played for any length of time is freeciv, which as the name implies is based of the civilization games, mostly civ2. It's a bit old looking these days and setting up multiplayer has always been a bit fiddly, but the gameplay is pretty fun imo.
I always used to love playing Freeciv years ago as I grew up on Civ 2 and Civilisation: Call to Power. Probably should try it out again on a modern OS.
Arguable if you can call it a game or not, but there is Overte. It is an open-source social VR platform. (without crypto so please no pitchforks)
As one of its developers I might be biased, but I wouldn't be one of the developers if I didn't honestly believe in the project.
