My experiences with Nintendo's servers have been largely positive... this game could always be different, but past experiences tell me it should be okay, with the possible exception of trying to play Japan...

Japanese site got a different video!!!!

 Ah, ok, gotcha. I've never actually played a game with the Wii online yet so I didn't know how well it performed. I just kept picturing a half second of lag throwing of my triple jump as I'm trying to get back on the stage.

wait, for my character list, should I count the the Japanese video?

^ yeah I think you should

i cannot wait for march 9!!
i hope to experience 0 lag

i somehow expected a ranking system, and i want it, but nintendo thinks different about this one :(

and this only to play vs people with your same rank, so every match is balanced, anyway is going to be fun to play with that you want and that you know

wow, snake is very "heavY" in the japanese video, he didnt wont because of the smash ball that kirby took 

ok

I love this update... Smashing across state lines is gonna be really fun... ATL, I'll own you... University of Alabama, I'll own you... UTK, I'll own you... Lexington, Kentucky, I'll own you, and your little dog, too... North Carolina, I'll own you... Minneapolis, Minnesota... well, you're safe for now, but Metropolis, Illinois, I'll own you, and your tourist trap of a town...

Disclaimer: Aatg885 does not condone smack talk before a competition, because one tends to get put in one's place for running one's mouth... Talking smack during a competition is OK, as long as one is winning... (still, you have to admit: Metropolis IS a tourist trap of the worst kind; I know, I've been there)

^ thats the smashing spirit

 I will defend Atlanta all by myself thank you, all of Georgia for that fact =D, you should send me your Wii code so we can make sure to play each other when the game is released.
