Should I buy Pokemon X, Y, Omega Ruby or Alpha Sapphire?

It's not impossible, but I don't see it happening. Downloadable content is not something you see very often in the Pokemon games, and it's not Gamefreak's style. It's pretty unlikely that the new evolutions will be added to the previous games since they also want to promote their latest games (ORAS) and by adding the new Mega Evolutions to the previous games, they'll pretty much throw away a solid reason for players to buy the new games.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
