SoE was awesome. However, I never finished it. I only made it past the medieval age (when your dog turns into that fruity poodle) and then quit on it. I vaguely recall being told to fly around the world map and look for glowing spots to land on, or something to that extent, but I never went any further than that.

And Illusion of Gaia was amazing. Why in God's name Enix never released Terranigma in the States is beyond me.
