Sounds fun. Anyways, if you have all of the tiles, I could make the areas. I might actually enjoy it, too.
Anyways, it does sound fun. But will you have all of the Pokemon from each of the 5 Gens? Will they look similar, probably using the Gen5 battle System?
I have a few ideas:
Distinguishable Pokemon (Different colors, maybe scars or other markings?)
Time System (What rate? x2? 6 hours of play equals 12 hours in game? maybe faster?)
Character Interaction (Include our group, we could implement certain texts at certain times, and maybe different answers or responses that could alter a characters' opinion of PLAYER.)
Pokemon Control Option (So they can interact/talk with our group's Pokemon)
I would love to see a little in-game Kiba, and his party (Especially since they don't ever go in Pokeballs.)
I would love to see that epic battle with Green Trainer implemented as a cutscene.
