As you may very well have noticed, most areas don't have many Pokemon listed as available and there's not very many species at all. Don't worry - more well be added! We have no intention of adding every single Pokemon in as found in the wild. Some you'll only be able to get through special means. But as for the others, they're going to pretty much be added as requested. So here's what we're going to do - if a Pokemon is not on the Black List below and not listed as available on the forums, post that Pokemon's name here. Most likely it will be added. However, no legendaries will be added as regularly available Pokemon, and fully evolved Pokemon may also not be added, although the pre-evolutions will be if you request, for example, Espeon. We're not going to make that available as wild, but we may but Eevee out.
Also, if you'd like to request a Pokemon be on the black list, you may do that as well. If you have a reason, go ahead and put it down. Or if you just think it'd be funny to make Bidoof really hard to get, that's good too. We probably won't add anything that's available as a starter, though.
Black List:
Bidoof
Diglett
