oh, and a heads up: unless you have a DSi, there's a good chance you won't be able to use wifi/connect to the internet. the main things that matter that you'd be missing would be the dream world/game sync (dunno exactly what that is), global trade station, and wifi battles.. but the main game is still there, totally playable if you have a friend that has it. just don't go hoping for internet.. unless you have a DSi. in which case, go nuts.
Why?
