So in this new forum, just wander around the towns and routes while you choose your starter and ways to go further. Maybe you like to rp, maybe you don't, take it as simple as you like, take it however you like.
There might be only one restriction, and that is I'll make the wild pokemon appear and maybe how they react when fighting or catching, because otherwise wouldn't it be easy? Maybe I'll act for some gym leaders' pokemon too (some npcs if you'd like), other than that, good luck and have fun, the limit is your imagination! Kind of.
