Two games, both were Playstation (PSX).

One: RPG. You chose to play as either the male or female character. You obtained abilities by killing monsters. The guy could transform into monsters and the girl learned magic spells.

Two: Don't quite remember a lot of it, but what I do remember is a turn based combat system with the same basic grid battlefield system as Final Fantasy Tactic. There was a "rock paper scissors" involved when it came to attack/armor types.
I think the first was threads of fate. I remeber the male kept getting mistaken for a monster by a little girl.

Does anyone know the name of of an old disney race game for the ps1. I played the demo and I think you could play as chip and dale.
