Hmm, tough call. There are so many old characters from Capcom (to mention one only), like MegaMan etc. To me a character is more important in storytelling games, let's say Cloud Strife. Resident Evil chars aren't bad (Redfields, Leon), good old Ryu, Solid Snake. It's hard, in RPG you make your own heroes. Guessing it's them you play the most. Tried to give some from me above.
