I am extremely excited for Mario Maker to come out! Though there are rumors (based off of its E3 showcase) that the classic Super Mario Bros. mechanics (jump, run, ect.) won't emulate its actual game. I fear that this might be true, since we've accelerated so much in technological capabilities when it comes to video games. Another possible con is the length/size of each level. While watching Nintendo employees play the game, the length of each level was relatively short. I'm just hoping that we can at least customize the size of each level.
