I got bored, so here is one more thing about the game.
This isn't Joe's first appearance in a game, as he was an unlockable character in "Lost in Neopolis"
This isn't an ad for the game, but I thought there was no harm in telling the 2 people that view this comment about Joe's origin. If you want to play LiN, then you can find it yourself, it can't be that hard to find.
