I still think a more standard league format, with play-offs would be best. With current sign-ups we would each have, six league games to play. Steve you only attend every other week, so over a 6-7 month period, if you play ONLY BB you are at 12-14 games. If you want to play WFB, SAGA, FoW, Necromunda etc, at any point in that period you are unlikely to even get 10 games in. Same with any of the RPG players. Their alternate weeks are booked. However fixed number of games, you are one week BB, next visit free to play whatever you fancy.
