Agave Tequilana can be used to determine the end of a game if enabled with EnableFinish (default).
Starting at VoteTurn, players can vote. Each player's vote is worth their number of planets, plus number of cactuses controlled (i.e., planets with a cactus count double). The game ends when more than FinishPercent of all votes want the end.
To vote for the end of the game, send a message
cactus: vote yes
to yourself. A vote is "sticky" and will be applied for this and future turns. To retract a vote, send a message
cactus: vote no
You cannot vote for the end of the game while you are still building cactuses. Any build command (temporarily) invalidates a vote yes.
Alternatively, the game will end when someone reaches FinishScore.
