Cool! Just today I started getting some ideas for an actual setting. I'm thinking college aged characters, in a unique setting where the Ghostbusters aren't a thing yet. The characters also aren't the original creators of their equipment, so one element of the story is watching the characters learn to bust ghosts, and they'll need to, because the original creator of the equipment is somehow weaponizing ghosts, and the equipment was part of their evil plot. Still interested? P.S. I know that was a really long sentence, my writing is normally better than that.
