Thanks for the support! I'll do my best to get a challenging game you all can enjoy.
I gave the Pidgey's line Adaptability because I wanted them to be stronger, because it makes them better... You know, Pidgeot's normal abilities suck (Big Pecks, Keen Eye and Tangled Feet), so I gave it something different to make it stronger, there is no other reason.
Ok, I've finished Nimbasa City trainers (well, not all the dome ones have been touched yet, I have only edited the ones you can battle when you first get to Nimbasa.) Now I am editing Cheren's battle in Route 5. Wild Pokémon have been edited up to Route 6, as well. I am also elaborating movesets for some Pokémon. I hope to release a new Beta (1.2) this week, but I won't be able to implement moveset editing, not all, but there will be a few changes.
