Have you tried free writing about it? It sometimes helps me to just throw out ideas onto the page, regardless of whether they're good or bad.
For example, a cool virtual reality experience might be to go to a theme park with a roller coaster that's way bigger than could be built in real life. Or visit a zoo full of animals from the past like dinosaurs or even animals that don't exist like unicorns. Or a huge simulation of the galaxy that would let you fly to any planet no matter how far away in a matter of seconds. Or maybe a virtual shooter like Halo. Or a sex simulator that would let you have sex with famous celebrities. Or visit a period in history like the middle ages or ancient Egypt
Don't know if any of those are good ideas or would work with TG, but hopefully they'll stimulate your imagination
