Oh, so if Nintendo had the possibility to make the game 1080p/60fps with AA, while everything else stayed the way it is right now, they would have opted out of that and kept the game 720/60 with no AA? Jesus, do you even realize what kinda bullshit you sometimes write while trying to up talk Nintendo?
first, watch it.
second, when looking at MK8, one doesn't think: "the resolution should be higher" or "it needs AA" or "it needs better AI". I don't even think people would notice the increase in resolution, let alone this "no AA" because there aren't jaggies.
Now answer: if you can't notice jaggies, why complain about lack of AA? if the resolution is amazing as it is, why complain it's not higher (when it wouldn't even be noticed)? Thus, those areas weren't compromised.
