Super Paper Mario
The newest chapter of the Paper Mario story isn't just out of this world ... it's out of this dimension. What at first glance appears to be a 2-D side-scroller ripped straight from the stylized pages of the Paper Mario universe soon turns into a hilarious dimension-shifting platformer possible only on Wii.
No unfortunately. It just has multiple character to play as.
Yes there is, when you level up attack and defense increase. Though that's not the main mechanic of the game.
No. Definitely no. I bought it thinking it would, because of the picture it was advertised with (the original case) but what I actually got was a box with a paper slip and game inside. No case, not even a DUMMY plastic case and printed picture of the original cover taped to it. Do not buy if you are trying to get a nice copy with its original case.
No, this wasn't a wiiware game and the wii shop is discontinued.
