I don't even know if my country gets it on the following week, besides, I don't live anywhere near the big cities (nor do I recall having a GameStop shop or anything among gaming stores when I visit those cities).
I don't have it, so I'm not sure. But if it means what I think it means, then you need to unlock everything in the top row of the challenges section. Like in Brawl, where you had to do specific things to get trophies/soundtracks/stages/etc.
I spent 2 hours last night unlocking all the characters. What I did was set the damage to 2.0x and stage to automatic, items off, and 1 stock. Just 1v1 level 1's and after 120 fights you unlock everyone.
I love the new game, i say its the best one yet!
Im not getting the Wii U version cos i dont have a Wii U, but i think the 3DS version is a great substitute.
im very confused tho, why is Kalos Pokemon League on Wii U version? Pokemon X and Y is on 3DS
