GameStop's fine, they just aren't experts. When I was a kid I tried to get Super Princess Peach from the one in my town and they told me that game didn't exist, my mom ordered a copy all the way from Japan for me to have for Christmas, come to find out the game *was* already out in the USA, and they had copies of it in the drawer but not on display
Anyway, I pre-ordered Labo on Amazon lol.
