Tell me when they release a Pokémon game with every Pokémon able to be captured in one. Then I'll be interested. I honestly wish they would just start making them expansions instead of completely new games. I can sort of see the reasoning why they don't (features don't mix) but I can't stand how you basically need to buy every game to get all the Pokémon, and even then, you have to spend ages transferring them from one to another and even then there is a good chance you'll need to trade with someone who managed to get a Pokémon at some kind of exclusive event.
If they someday make a console version of this game I'd probably be all over it. But they won't. Sigh.
