I think we might need more players to make the game sustainable - we need 8 active players (J!Aer and J!Aed, up to 5 voters, Ref) for any game, and I think that's all we've got. Someone goes out for the afternoon and we're out.
Potential rememdies that come to mind include:
- extend the Heat Death timeline,
- recruit from other boards / friends, or
- increase the reward for voting.
