so, I think I'll be able to get a pokemon game thanks to the club nintendo promotion, that is if I don't have any problem with the registration... so I'm deciding which one I should go for. Pokemon emerald is the last (and only) game that I played so I don't know much about the series, I thought both games were virtually the same but then I checked the wikipedia page and saw that pokemon y is slightly ahead of pokemon x on both gamerankings and metacritic. I'm not that picky to care about one point in an extremely subjective scale but I wanted to ask if there is something that makes one game different from the other so I can choose the one that suits me better.

thanks for all your help!

The real choice you must make is not whether you pick X or Y but which starter you pick.
