To everyone complaining about SMW: Do what I did. Just put SMB down until everything is out of beta and officially released. It's not like there isn't enough other awesome crap out there to play right now. I haven't played Meat Boy in at least a month and the urge to play it is coming back strong. By the time the editor is official, the problems will be fixed and the drive will be back.
I mean, if you haven't played through Portal 2 at least twice by now, you're just crazy.
Mortal Kombat isn't half bad either. Now we just need PSN back so I can razor-rang some faces!
In its current state, the editor is as official as it'll probably ever be. There's even a disclaimer on the level editor which states that "the level editor is in beta and probably will be forever".
So yeah, things are about as complete as they'll ever be, hence why people are complaining.
