Hmm, how should I start this? Well, first I'll list the anime/games/etc that I like to RP... No, wait, don't leave yet!
Legend of Zelda
Magical Girl Lyrical Nanoha
Tales of Symphonia
Canon or original characters are fine in any of these.
Now, below is where I will list plot ideas for the above as well as original plots. So far I just have one
Surprise at the Auction (original; VAN, BON?)
A girl has her eye on a particular guy, but she's never been brave enough to talk to him, instead watching him from afar. One day there's an announcement for a bachelorette auction. She looks down on that sort of thing, but the money spent goes to charity, so she decides to join.
Once on the block, who should bid the highest but the one she has a crush on? And as it turns out, he has a thing for her as well...
