I don't mind High School/Magic Academy RP's and stories, I am a fan of Persona after all. As for which scenarios are my favorite; I prefer stories about a small group of 'Super' Students who keep their powers hidden instead of say, Hogwartz. I don't know; a hidden magic/super academy just doesn't sound terribly believable to me. Plus; if I myself had magic when I was a kid, I'd rather be apprenticed to a more experienced Mage, or improve my ability on my own. Maybe I'm just drawing from my own experiences, but yeah, not a big fan of a school where the bully can melt your face.

As for which scenarios I'd like to see... 

I would be interested in a SMT/Persona-styled rp where you play as High School students out in the Japanese countryside... After the nukes hit. Facing off against Demons running amock, refugee swarms, rabid techno barbarians, food shortages, water contamination, and the omnipresent threat of radiation. And yes, I fully understand that this would essentially be running on ultra-hard mode the entire time, to say nothing of being VERY depressing. >:D

I would also not mind seeing a RP where you play as teenagers in a lower tech Shadowrun. I mean; Steampunk Shadowrun. That's awesome! Of course, such a scenario would probably work better with adults but I certainly wouldn't mind parodying Greyfriars, or Tom Brown's Schooldays.
