Hey guys i am really sorry for my english... but here we go.)
So the main thing that i want to know is how laggy online is? Because in the end of a day i want this game for one MAIN reason,is to playing online casuals with my brother, that's it . What i mean, online casuals? Modes like : 2v2 (free for all), free for all with local player (my bro) with other humans, ranked matches etc. I think you get the idea.So please if you can answer to this questions, please do it.
And one more mini question) How online is in this game compared to MK9's online?
Ignore that first guys response... the online for this is amazing. Like the 3rd poster said, 3 issues out of 50-60 games. I'd say about 5-10% of games I have played I have had lag related issues. That is a very small amount considering I am playing on a Vita.
Compare that 5-10% to Smash Bro's Brawl, which I would have direct internet via ethernet, and 95% of my games I would have lag related issues. I literally had 1 playable game out of 20. There's no comparison really. The online for this game is fantastic, and I had a very positive experiance with it in the beta, which is why I decided to buy it in the first place. If you're getting this game to play online with your bro or even random people, I would highly recommend it!
