I know, but at least it`s the only exam I`ll have this year
You`ve got neither of the newest Nintendo systems?! You really miss out on some games then...
Personally I recommend that you get yourself a 3DS as it is already clearly established as a great success while the Wii U already show signs of being another flop from Nintendo and might disappear pretty quickly just like Advanced, SP, Game Cube, and some of the previous DS versions.
Actually not a bad idea! Would have been awesome if you could switch between the characters while playing so to get better use of their different abilities. I remember one of the old Castelvania games being like that and because of that feature it was my clear favorite
