[color=silver]Personally, I'd like to see, and in no particular order;

Mai HiME
Harry Potter
Fruits Basket (minus spoilers! *glares at spolier-people*)
Pokemon (yeah, *shrug* just don't ask)
The Next River *Glares at Jobes then realises that she's supposed to be co-creator* ...
The "Modern RPG" *more glares* you know what I'm on about, Plantae-boy.
Final Fantasy, preferably X, but that's been done so many times...

All of these are in my list-of-potential-RPG's-to-make-when-Otherworld-finishes...

so yeah, they're a while off ><
