- Raichu isn't on the list because of Yellow version. You had to trade for one since Pikachu never evolved in that game.
- Psyduck and Golduck aren't here because of Leaf Green only.
- Same goes for Koffing and Weezing except it was in Yellow version that you couldn't catch it.
- Stop bringing Ditto up already. It wasn't in Ruby and Sapphire like BHwolfgang mentioned. That was one of the main reason I hated Ruby and Sapphire since it was annoying to breed in that game before the other 3 Advance games came out.
- Pokemon from the second generation and up aren't on the list for very obvious reasons.
I also wonder if Alakazam, Machamp, and Golem should still be on the list. You had to trade to evolve it which kind of defeats the purpose because you might as well trade for Pokemon not available in your version if you want to trade just to evolve your Graveler/Kadabra/Machoke.
I hope I didn't miss anything. :/
