Thanks :) I'm heading back to the RBY years (Gen 1 and in Kanto) but with information from all the generations all the way up to gen 5 (BW/BW2). The only bit I'm having trouble with at the moment is adapting natures in to the story -- natures raise one stat and lower another (e.g. a pokemon with the bold nature has its defense raised 10% but attack lowered 10%) which is all well and good in the games, but a bit more tricky to put in to the story.
