I've never actually played a Pokémon game before, but I'm curious. Exactly what is the point/difference between the whole "parallel release" thing Pokémon games seem to have going, and what is the difference or link between these two games? (e.g. X and Y; Ruby, Sapphire and Emerald; Black and White)
I ask this because I'm thinking about getting X or Y for my 3DS, and obviously asking if it's worth it will be pointless, so I'll instead ask if there's any point in getting one over the other.
