Xonotic is good, but somewhat dead. There's not a lot of servers for it.
Pixel Dungeon is a mobile game, which was recently made open source, and is on f-droid. It's really damn good, not just good compared to open source games like most games, it's actually good as a game.

And while the art isn't open source, the engine I use to play it is The Elder Scrolls 3: Morrowind.

Simutrans (transport simulation)
OpenSpades (Open source Ace Of Spades client)
Astromenace (Arcade space shooter)
Also Minetest. BTW, maybe someone can suggest some quality mods for that?
And I will leave this link here just in case.

My sentimental favorite is xtank, although that was decades ago, and I haven't tried to see if the Linux version works.
