In one day you pumped out three interest check ideas. I'm wondering if you should probably lay to rest your GM dreams. Especially since you shut down all your other attempts.

If you really want to improve your "world building" try joining in on existing RPs. There exists a balance of population between GMs and players which you're obviously overbearing with the same ideas. Please, join more RPs. You obviously have the time if you think you can GM one or three or five. So please, just join an NRP.
