Debated on posting another suggestion since they're usually ignored or people don't like them. Anyways, it would be interesting I think if you could alter the age of your character's appearance and not just have characters that appear to be in their 20s. ( I know you can change hair color and height to make it look like their old or young, but I'm talking facial appearance-wise etc. From youths to as old as Matoya's wrinkly face.)

Another suggestion would be something from the GameBoy Final Fantasy sub series games. There was one instance if you beat a monster they'd leave meat, and if you chose to feed it to your character they'd turn into that monster. It would be cool to see player characters roam the worlds as monsters randomly. One could even role play more that way.

Anyways, these are some of my ideas, probably will be ignored, but oh well.
