It sounds kinda strange for you to be comparing a system that's barely been out for 2 month to another that's been out for years and built up a library over time. Give it time, it'll get more games.
Also, sorry to hear you didn't enjoy MK8 ;_; Maybe you should try playing it with friends. That's a lot of chaotic fun.
Dance my pretties!
