I dunno if this is remotely reasonable given how hard it's been to get any sort of #RP group going in the first place, but I'd love to eventually set up something that's set in the Kirby universe (but not necessarily limited to it character-wise) - I got to play with a group in 2021 that showed me there was a lot of potential, but also that would take a new group to actually reach that potential.
There's a lot of fun locations and I like the very videogamey depictions of Pop Star with very prominently themed areas. And Great Cave Offensive and Milky Way Wishes provide some fun whimsical places to visit, that could be built out further with more worldbuilding. And it'd be fun to play as Elfilin somewhere, whether or not in a Forgotten Land area.
