maybe add a mountain, where you could be dialga, palkia, (maybe gender based) and arceus if you get an azure flute, for getting money, maybe a give poke dollars verb, or the abilty to start up shops. maybe being able to play on the nintendo ds and other consoles.
and a proper grass tile/floor instead of having to use jungle floor for it. maybe you could become groundon from volcano, or kyogre from underwater. more items. and more pokemon to become. that rare island, maybe you could get a rare thing from it, and it sells for alot?

Alot of Good ideas we will take them into consideration
