Well, after a couple of hours I get why this game might not have as much appeal.
You feel just really stupid either way when the river completes a flush and the villain bets for the first time... you can't exactly fold. The number of players willing to chase 5 outs is just incredible, it's really hard to stomach all those beats.
Not to mention that it's just a brainnumbingly dull game... I might play the 15/30 again. That was fun, but sharing every single pot with a minimum of 3 players seems pretty pointless.
