I thought we were done with the NSMBW should've had online stuff. I warped back to November 2009 again. No one here complains when local muiltplayer is taken out for online. But when they take out online and have only local muiltplayer. Yeah we all know this is just a excuse to attack the wii. I could do the same with the other systems

I'd say it's quite stupid to leave out local multiplayer. But what's that have to do with anything?

How does the game selling well mean that they shouldn't have put in online? Why does wanting online mean that you can't also want to play with friends and family? why is someone out of touch for wanting a feature that's in the vast majority of games now a days? a feature that people love even in other Nintendo games. People here love Mario Kart multiplayer. And they'd love Mario multiplayer too. But here are some things that would happen If NSMBWii had multiplayer (and it could still come out in time for Christmas); There would be a VG chartz Mario online league, and dozens of people on here would be happily playing the game together. 

I could play with friends that live in other cities. To those that use the "why don't you just play with your friends", I say you're very lucky to live so close to all of your friends. Lots of friends and family would love the chance to play mario together even though they can't always be in the same house. And if you could use Wii speak... That would be fantastic. 

Having online multiplayer doesn't mean that everyone can't ahve the exact same local multiplayer experience. It just means more people can play together and more people can have more fun. Why would anyone argue against more people having more fun?

The point is, for the game to work well online, it'd have to be changed.  Changed in the sense of the physics, the pacing, the stages, etc, so that it wouldn't fell broken for most people. Now, that means they'd have to make a different game, and that's not the game they wanted to make. The online multiplayer was not even close to being more important than both the singler player and local multiplayer so that they'd re-shape the game because of it.

The alternative would be to actually pack two games in one, so that online would control different and all that, but that'd not only be a lot of trouble, it would feel off and unpolished, unless they took a lot of time on it, wich simply wouldn't pay back and would push the game back, wich would be very bad not only for the game, missing the holidays, but for Wii overall. And it'd most likelly still not be nearly as good a mode as the others. So, yeah.

^^What exactly would they have to change for online to work!? The game can have one to four players. Whether the players are sitting in one, two, three or four rooms doesn't mean the platforms have to be in different places.

Here's probably what happened: Nintendo is too lazy to do online and hides behind the agrument local multiplayer is the only way to play it with other people.

It would have to change so it's not as affected by latency and sync problems etc, the way it is now a lot of people would have some serious problems with it, so it wouldn't work well. I know, LBP works, but LBP is a lot different in basic design, and that's the kind of difference I'm talking about.

So basically, they predict the EXACT moment you would have lag and make the platform just a little lower?

I don't think that's what I said :P

But it has to do with things like speed, size, and precision, I believe. There are ways to "mask" lag (at least small amounts of), but the shorter the timespan of your movement and the more important precision is and the more controls you have over it, the worse it'll feel.

Tons of different games over different genres play just fine. Mario isn't somehow exempt. Aside from the "might delay it past a holiday season release" argument (which is an excuse, not a reason), there's no logical reason to leave out online play.
