The idea for the game sounds good. However, I'm in the business of looking at the negatives of a game before I look at the more obvious positives.
I don't know how or think this type of game could be done using a computer interface like most of the other games (exception being Cafe Blackjack). In order to make sure people don't use a RB more than once, you would need a moderator willing to check everyone's list each week to make sure there is no funny business. I mean, you want to trust the membership to be truthful, but you never know.
The other negative is that we already have a bunch of games already. Yes, I know they don't take long to play each week, but at some point I would think you need a limit on games. I get burned out trying to make sure I fill out the stuff for the 4 we have already.
MCG does a really good job with the Blackjack game, but I'm sure he can tell you that it takes a decent amount of time to take care of the game. If you'd be willing to put in the time to make sure everything is scored correctly and all that, then I suppose it would be a worthy consideration.
