Some ideas for the script. Make player visit rival house, she talks about she will rise higher in Magma ranks. Then player visits Lab and gets Pokemon. Birch is called Magma Leader {something that sounds firesh, you decide}. He is at lab and tells about Magma mission to destroy Team Aqua. Player moves on to Route 1 and battle 2 weak trainers. 1 has Rock pokemon, the other water. release a patch for this. I will add my update soon.
Thanks.
