This is also what happens in the original game when there are many more pirates than coins. If we assume there are P pirates and C coins, where P>2C, then stable groups form when (P-2C) is a power of 2, with those highest-ranking pirates getting no coins but voting for their own survival, knowing th...

Vast is pretty well balanced, but essentially each player is playing a different game at the same table. The teaching takes a while, and if you want to switch roles for a second game you practically have to teach it all again. Overall I liked it a lot, but it takes some dedication to get into it.
