What Luke said. Being busy is another matter entirely, but if you're worried about your level of practice it shouldn't be an issue in this game. You did quite well in Ninten*'s Mafia anyway. I'll put you down as a replacement but if you'd like to be a starting player don't be afraid to ask!
Thanks, Austin! I'll stick as a replacement for now, since some of the other games (Beginner's) are still going.
