Ah, so a normal session of sburb is a game of chess, but since a single player session is run by different rules, it’s a game of POOL.
Caliborn said he’s DESTROYING the planets as he goes along.
He’s pocketing them.
He’s the Cue Stick, pocketing the pool balls one by one, until he’s won the game.
That’s why he’s going to have to fail the eighth planet and not get a minion from it (Which is why he later has to get Sn0wman), if he pockets it, then HE LOSES.
