Thanks a lot Hikari, Sydian
Well, I did a little search about your recommendations, and I decided to start off with white version (black and white), Since I'm new to Pokemon I think i need a great story that can make me go on with it and complete it at least to let me play the others.
To be honest, The reason that made me ask that question is black and white, I read about and saw some interesting characters one that loves ferris wheel or something.
In anyways, I'm going to order a list Black and white and B2 and W2/Platinum/HeartGold/SoulSilver
Now! I'm grateful for knowing such a good community. I'll try to discuss my playthrough with all of you.
