Ah the turnover mechanic is the best thing about the game! Makes it so infuriating/brilliant.
There is BB3 out now which mirrors the current rules but it's not been popular, mainly because it's a horrible buggy mess still and the interface is awful, so it's kind of killed the online scene compared to BB2 unfortunately.
The tabletop scene is really thriving though, the last World Cup last year had over 2000 people there!
Nerdddddds!
