Hey, I'm actually trying to come up with some! So far:
A roleplay about a friend group who suddenly finds the ability to reverse time.
A roleplay set in American college. Character A's grandmother died, and suddenly they inherit a bakery!
The comedy roleplay but set in a business.
All the characters are on a plane, and the plane crashes on a desert island.
A bunch of high schoolers try to make a rock band.
A roleplay entirely set on an instant messaging website. People can join any time, because the website is similar to wiki chat except that's the entire website, and it's pixelated for *aesthetic*. The interface and stuff looks like EmilyIsAway, and there's profiles and stuff.
Mary Sue Land. A bunch of Mary Sues are stranded on an island without any resources and stuff. No magic and stuff, keep it realistic but stupid as possible. Like don't make them shout up to heaven and make fire appear, make them somehow no exactly how to light a fire and do it on the first try perfectly despite not having any knowledge in the field and the fire's perfect and good as a home professional fire and it could've been lit by a match or whatever makes perfect fires etc.
