Hey guys! I just have a little problem. I got kingdom hearts 3d and I'm loving it so far and I kinda don't understand some characters and story. Like Sora, and two other boys are like the same in features. Is there a relation? I think they are Sora, Roxas and Ventus. Now the reason I don't know any of the characters is because I didn't play all the games. I've only played Birth by Sleep. I just need a brief explanation of kingdom hearts of all the games and about sora, roxas and ventus. And plus who is Xehanort? And the Organisation. Thnx!
