whats the online like in the game? is it any good? because i havnt seen any one said how good or bad the online play is since its released worldwide, i have plans on picking it up next week i just want to know lol,

Today i have to pick up my copy, so later i let you know how it is

The online is great. I just played about 3 matches and had no issues at all.

Good.

is it like mario karts online?

I would buy it very soon.Good thing you made this thread!

Check the Gametrailers Review for a more in depth info on Online.

it's good no lag alot better then brawl

Do they have a rankings number online so we can get an idea of how people have purchased it so far?

I've played 20 matches, 19 of which ran flawlessly, one was laggy, but 19 of 20 is good for me 15 wins to 5 losses (14 of the matches were really competitive, the laggy match was a blow out loss for me)
loads of variety among teams and loads of fun
I've been messing people up with the Tekka twins (I absolutely find these guys incredible), Silver Lightan (cool extra on Capcom's part), probably driving people crazy with Joe the condor and with my main Roll plus an inconsequential second wreaking all sorts of havok, seriously she is incredibly good for keeping opponents off balance and her level 3 HC is second only to Polimar's to damage, out of the 5 matches I've won with her I've needed to touch my second character once, and those 5 were against players with scores between 1200 and 1500
anyway my advise is learn Roll, nobody sees her coming and she's a blast to play as
