Is the idea for just the game to be FOSS or for the characters to be related to FOSS as well? IMO, the latter would be a good limitation to start with, which would be in the vein of Super Tux Kart using FOSS mascots.
As for names:
- Super Tux Arena
- Super Tux Royal
- Super Tux Take Down
- Tuxogedon
- FOSSogedon
- FOSS-For-All
- Ultra Mascot Feud (UMF)
- Merge and Conflict
- Tuxus Rumpus
- Liberty Wrangle
“Don’t care, just buy”
- Gamers
