This is an excellent video. This guy, Eddie Parker should be the face of Project Spark talking about the game as he did an excellent job in breaking things down in the vid, so fluid and convincing.

Looks alot like what I'm using to build my tablet game currently. So I can see the possibilities being not quite so infinite god forbid you need to do something complex like run a loop lol. But if they add in the ability to add Kinect 2 gameplay and features I will forgive any imperfections. I wonder if Kinect 2 for windows will be compatible with Project Spark on Win 8. May not have to get a next gen console afterall.

I doubt there's a marketplace. All the games are free. Plus you can download other people's games, make some changes, and upload as your own. They might put in something restricting that loophole like but nothing's been announced afaik.

You can do as you wish with whatever you create.

No you cant sell your games. Others play them free.

Are you absolutely sure? "Do whatever you want" from the devs means that. You might get funds to make a project and then release it to the public. Or accept donations. In those two cases you're getting money.

Its not like that. You can mod or change others creations. Its a Free 2 play game. Only money that gets exchanged is buying further content for building. You cannot change someones creation by 1 tree and sell it on. Its Free 2 play.

like it will spark to life maybe :D
