Online has SERIOUS problems with lag. I have had maybe 10 minor lagged matches out of the 70 or so I've played so far.
To all those E.Honda wusses out there that think they're good because they figured out how to use hundred hand slap and how much damage it does to someone standing or blocking; I've fought about 8 of you so far, all with the same technique, and I've kicked the living $*17 outta every single one of ya. Bring it.
The achievements make it pretty fun to play through and again; and hopefully if they can fix the online lag problem, this will be a much more fun playtime in the future. After a few matches (if you can actually get one without timing out), you will still have a bit of lag, but have enough time to adjust to it, and still have fun.
