Paper Mario Sticker Star E3 Demo Two 3DS Mario Titles Demoed Today at E3If I asked you to name a Nintendo franchise, Mario is probably one of the first names you’d think of. Nintendo knows this, and that’s why they focused on two games starring the iconic plumber at today’s 3DS mini conference. First up was Paper Mario Sticker Star, where a gameplay demo showed off the familiar 2D graphics and platforming action from the first Paper Mario title, along with all the new possibilities that come with the addition of stickers. After that, we got to see both the single player and co-op gameplay modes of New Super Mario Bros. 2 in action. The demo content from both games is inside.
