I opened a board game/trading card store in May. We host events and sell products. Takes up a lot of my time but ultimately it's a passion project that actually makes money.
I dunno if it's in your wheelhouse, but I recently discovered a "game cafe" locally that allows folks to check out games by the hour (like a very specialized library), but they also sell beer/wine/coffee/pastries plus running the events like you said. I am so incredibly sad I didn't think of that first - that forehead slapping moment is my definition of a "good idea"
