I think they have a basic event framework. Think about all those side scrollers out there, working with the same physics and layout - with almost unlimited possibilities. It's like myspace layouts + flash gaming. I think people will love it.
I hate to be the naysayer on this, but I disagree. An ugly MySpace page is interesting because your friends are on it. A bad game your friend made is still just a bad game. People who are talented enough to make good web games already have a tool to do it with - Flash (typically a pirated version). It's not a perfect tool, but it's very flexible. I agree that the physics in this thing look great though.
"An ugly MySpace page is interesting because your friends are on it."
Exactly! :-) We believe people will want to play their friend's games just like they want to see their friend's MySpace page. The reason they got into MySpace in the first place is because they could express themselves through the layout of their page.
