Ah, simply Isaac from Golden Sun.
So many people were hoping for him anyway. I was one of them. A lot of people were disappointed upon release when they figured out there was going to be no Isaac in the game. That's how the cookie crumbles, as the saying goes, I guess.
You just gave me a tough decision which I cannot make. I would have loved to see Crono in it, but at the same time I would have loved to see Isaac from Golden Sun.
