You should start Twitch mini-movie theaters which communities can rent for tournament streams.
I've had this idea lingering in my mind for a while, so figure I might as well toss it out to you guys! I think it would be supremely cool if there were such a thing as Streamer Theaters, in which communities could gather to watch their favorite games play out on a big screen. I know the Smash Bros community would be a huge fan of that at the very least, especially if the venue could accommodate their own setups so they can play while it's happening (definitely wouldn't recommend a fully traditional theater setup for this). It's the sort of thing that could honestly really impact the entertainment industry on a large scale. These games are our "football" or "MMA" gatherings, and lots of communities would love to have official places to gather for them, I imagine. Just gonna throw this out there and see if someone with power picks it up!
