The aim of the map follows that of the game. Go through Johto, collecting all 8 badges, and battling the Elite Four. From there, you can access Kanto, and defeat the original 8 gym leaders. After that, you make your way up Mt. Silver, and challenge the game champion, Silver. Along the way, you can pick up Pokemon eggs, sail across the water, use custom-redstoned Hidden Moves, and much much more! I guess you'll just have to see it all for yourself.
