I am looking for a game. It was for Dreamcast, Gamecube, Xbox, or PS1. It was an RPG. All characters in the game were associated with an element, Main character being Fire element. There were 3-4 PCs, but game over if the main character died. The elements were paired opposingly, IE: Fire weak to Ice, but also Ice weak to Fire. One of the first bosses was a giant amoeba, and the final boss was an Ice Queen type.
