C'est la vie. 
I know the glory of ALL FOUR MAIN DISGAEA GAMES!!! (Well, their cutscenes and stories anyways. Not the gameplay...)
Awesome! 
...Now that I think about it, if we're playing as versions of ourselves, then maybe doing research isn't necessary. One of our characters could fill the other in on some details and have advantages while the other would be disadvantaged. That would make the RP quite interesting. XD

Some fandoms I suggest:
-Undertale
-Tales of Vesperia
-Tales of Symphonia
-Final Fantasy (VII, X, X-2, Tactics Advance)
-Magi: The Labyrinth of Magic
-BBC's Sherlock
-Phoenix Wright: Ace Attorney
-Alice in Wonderland (Normal and/or American McGee's and/or Looking Glass Wars)
-Castlevania (Portrait of Ruin, Lords of Shadow series)
-Puella Magi Madoka Magica
-Steven Universe
-Gravity Falls
-Pandora Hearts
-Black Butler
-Soul Eater

I'll post more if any come to mind. ^^
