Okay, first of all, I don’t want to get controllers out of the game. I just find it boring approaching an airport that only has a UNICOM frequency. Some research would have to be done beforehand, such as finding airports that actually are controlled (this would match real world ATC conditions). When a controller wants to enter the game, they will simply take the place of the AI. I think that it could be a cool idea. Please let me know if this is a duplicate so I can take it down.
