The FGC is just run on a different model than e-sports. I've always said FGC is closer to WSOP than any "e-sports".
One idea: 12 tournies (majors) do this.
(My suggestion: Evo, FR, UFGT, NEC, NCR, SCR, TFC, Devastation, a Texas tourney, CEO, Canada Cup, NWM)- go for a good geographical mix.
1st place goes down to 30% from 70%. They put 40% of their entry fee money aside for the grand tourney.
At the end of the year- the 12 winners (if someone has already won and wins again, the highest eligible finisher makes it)- play round-robin somewhere for all that money. pot bonus includes free trip to grand tourney. YOu wouldn't need a big place, it's invitational- at most 75-100 folks would need to be there (players, staff, commentators)
You'd probably have a pot of around 100k for this grand finals tournament, held new year's weekend.
