Hotel Mario - Duh... It looks like crap, and isn't very fun at all. Very dull and boring.
Mario Kart Wii - Lol, there isn't much wrong with this game, I'm just not good at it. I find it annoying and aggravating.

Dr. Mario Games - Dull, uninteresting, not to mention I'm not good at puzzle games.
New Super Mario Bros. U - By far, my least favorite in the series. Just because it's in HD doesn't change the fact that it doesn't really deliver anything new, and is really familiar.
