Okay, I did a search, and precisely one person ever has attempted to adapt Pokemon? In 2008? And got around six posts? I feel justified in starting another.
Our campaigns are such that playing an anthropomorphic shiny eevee ninja as part of a group of soldiers, erm, went perfectly normal. One of the players even failed to notice I was playing a pokemon, which does not speak exceptionally well of my art skills. He was pretty gritty for an eevee, though.
So my ideas here are threefold: Racial classes for pokemon, a trainer-like class (least important really, horses that leap over skyscrapers = plenty fun on their own), and perhaps pokemon-emulating class(es) resembling totemist (because leaping over skyscrapers when you're not a ponyta = also fun).
With at the minimum 151 pokemon, and probably more since I like dark pokemon and will need at least 2nd generation for that, ... how might I attempt this and not burn out? What would be a good model to base racial classes on, or will they vary too widely between Ponyta, Abra, and Tentacool? Should evolutions be prestige classes unique to a single race of pokemon, which is kind of weird? Obviously Espeon and Bellosom aren't going to get the same class features...
I'm going to keep brainstorms in the next post, and if I write anything comprehensive, I'll put it in a new thread with a halfway proper number of posts.
