Ah, Steiner...he was as lovable as they come. To me, anyway. I couldn't get enough of him. Story-wise, I thought he was brilliant. Game wise, I also thought he was brilliant; I used him to the very end of the game. With all of his sword attacks learned and the Excalibur, he easily made it into my main party.
He was, well, awesome. I admired the personality in his character, very much so.
