Hopefully this is more than an theoretical question (because that would mean a very healthy Armada scene), but I'm curious:
How would you handle a Corellian Conflict Campaign league if more than 6 people want to participate?
I'm sure there are plenty of community's that might struggle to get that many people to come out. Yet, in my experience with X-Wing, a league really helps people come out more and it boosts attendance numbers at the weekly game slot at the FLGS. So, what if it is likewise wildly successful Armada? Would you cap the participants at 6? ("Sorry, number 7, go play with the MtG kids!") Or, would you get inventive and figure out how to accommodate more people than the RAW cap of 6?
