I hate that Super Mario Maker turned out so bad. I mean it's so much fun, it was such a good idea, but it's been ruined by bad level designs. Hopefully when the next Mario game comes out no one will say, "These levels are too easy. A baby could do this." Because now we know how hard it is to make a good, fair, challenging level without it being bulls*** hard.
Yeah, Super Mario Maker did have issues there. Which to be fair, is a problem with user created content in general. There's always far more crap than good stuff.
