I think Johto is just hte name of the league or something.

And since I'm going to buy the actual game, I'm just gonna have fun with this. I'm not going to catch a single pokemon. Right now Charmander is level 10, making his way through Viridian Forest. The only problems I see ever are up ahead, badges 1 and 2 against Brock, rock, and Misty, water.

EDIT: Now my Charm is a level 16 Charl, who just kicked Brock's ass.
