Online is not really funny, with the so-called "top" players quitting when you beat them and also spamming infinites to death. What's even the point of playing like that? It doesn't require skill or anything to learn to do it, it's just a lot of practice and repeating. I don't see any fun in popping your opponent into the air and then juggling him for 70%. Where's the fun in that?
I did online once and then never again.
It lagged worse than MK9 ever lagged.
I don't know if it has improved since then because I never tried it again but it was utterly awful when the game was first released. I don't know how people managed to get their 200 wins. Just wow, man, that takes patience.
It doesn't lag like that anymore and you can get the 200 wins against the CPU, too.
Obviously the mangled online at release hurt a lot, but I think a lot of people downloaded this to play solo or with friends locally. There's something about old school MK and new school online douchery that doesn't really mix well IMO.
(not that anyone here is a douche online, but we all know how common it is)
