It really depends on your connection to the opponent more than anything,
Damn right it does. That's why I take impressiosn with a grain of salt. People don't understand how peer 2 peer works. They expect perfection when it is physically impossible. A persons experince may be totally different based on who you got matched up with, and the kind of connection they got.
Guy 1: Plays 20 games. All great connections. Guy1: The netcode is great!
Guy2: Plays 20 games. All wireless connections with 50-80% packet loss. The netcode in this games ass. Don't buy this shit. Mk9 levels yo.
Mk9 sucked because the match making WAS barely functional. I played maybe 5 ranked games. And that took a total of 1 hour to find 5 of those games. I just played in the lobby places, and had more fun. Those king of the hill games were clearly a sign of the system not being able to handle it. When I had a great connection, it was great. I actually hit 40-50% combos all the time no problem.
Anyway, I have to go out, but when I get back I will try the online asap.
