Woah what the frick?They limited what pokemon you can have, apparently on the basis of wanting to make it easier to balance.
Pokemon has one of the most hated videos. What did the game do?
Basically it's limited to the regional pokedex.
Which is a terrible decision for a franchise that has had the tagline "Gotta catch them all" for the past 20 years.
