What Pokemon games do I need in order to catch them all?

Not including special event Pokemon, what games do I need to catch all Pokemon?What Pokemon games do I need in order to catch them all?
You need pokemon from all regions. So Ruby and Sapphire (because there are some pokemon exclusive to Ruby and some to Sapphire). You can't get every Hoenn pokemon from Emerald. As for the Kanto and Johto regions, HeartGold and SoulSilver (for the same reason as Hoenn), although you will need to trade or start the games again for all the starters. This applies to all of the games, although you should leave one game (Black or White) game not reseted, so that you can migrate all your pokemon over to that one game and complete your pokedex in that same game. As for SInnoh, again you will need Pearl and Diamond as Platinum by itself won't suffice. Lastly, you will need Black and White.

Sounds unfair, and it is. Sorry to give you this bad news.
Let's see here...



You can basically catch them all if you have just Black and White. But, to do this, you need friends to come into your entralink and you need dream world. Otherwise, you'll also need the Generation IV games. However, there are some pokemon, like trapinch, that are very hard to obtain in both Generations IV and V, so, thus, you'll need to rely on Generation III games to get those pokemon. And that's basically it.What Pokemon games do I need in order to catch them all?
