Destroying Meeplecon 2018 and turning it into Globalcon 2018 should be your goal.
I don’t see why I should arrange a “structure” to find out before the “real” games begin.
Im saying since their is no rating system and many people who may play wont know how good they are, everyone should play in one big tourny, but the number of teams would need to be structured into divisions of which the winner in each play each other. no different than Basketball or any major sports structure of determining this.
Under that tourney you ran, you had two divisions, but the winners of these never met, because play between them did not exist. Only teams in that division played each other, not in the other division. I bet some team in Hobbyist could beat enthusiast, but it wasn’t possible. I am proposing you just have the winners of each division play each other rather than the top two teams in ONE division. Its simple, no?
