I still love that Dissidia has an easter egg that references him. If you max out Ex-Death's level, you unlock a hidden dialogue from him where he's just yelling "TURTLE!".

As for the game, I wish they had gone into more detail about the sage. Ghido was really interesting and it would have been cool to hear a little more about him.

Though I know his true infamy was always being involved with all the fake internet rumors of a hidden Paladin job class. Usually involved somehow getting back into his cave after Ex-Death trashes the joint and he hands you a missing crystal shard.
