There's been some confusion about Dragon Quest IX co-op play. Is it local only or does it using Nintendo's WiFi connection? Just imagine playing DQIX with faraway friends!
Square Enix PR clears up the issue with this: "From the beginning of development, co-op play hasn't been via WiFi, but rather DS wireless play."
So there you go, bye-bye confusion and bye-bye DQIX WiFi dreams.
