Regarding Malifaux, which is by the way on tonight see the calender above, we have a range of crews
I have Guild - Sonia & Justice & enough stuff to vary the crew quite a bit and I am finding that I am rather concentrating on the guild
I also have Arcanists - Rasputina & am working on an Outcastes - Victoria's crew. We have one player who has a preference for Resurectionists having all of them except Kirai, but who also has some Guild - Hoffman & Justice as well as Arcanists Ramos we have a Neverborn player who has just started but wants to specialise in that faction we have Outcastes - Somer -Teef Jones as well.
However don't let yourself be limited by what we have not chosen there is enough cool stuff in the game that no two crews even lead by the same Master need be the same.
The trick is to have fun.
