That's what I do not get about this show, but then again I do. I know about the Justin Baley cheat, but I've never actually beaten Metrioid before. So, I don't know. Bleh!
I think Arino was cast because he enjoys video games, but at the same time knows next to nothing about them. He's probably one of those horrible "casual gamers" that fat pathetic World of Warcraft addicts are always complaining about.
