Doom is always great. FOSS up to Doom 3, but you still need the full games for the assets. If you don’t have them there is still Freedoom. And The Dark Mod is a great free Thief like game on the Doom 3 engine.
Stronghold Defense mod is amazing. It’s basically a base defense game against hundreds of enemies parading towards you, with custom weapons and power ups.
The Dark Mod is certainly the best and most advanced OpenSource game I know (well, not full OpenSource, because the user created missions, currently 170, are with several CC licensed assets, released because of this as freeware)
