Fantastic Contraption was released by accident in the UK recently. An early build was uploaded to the playstation store and i bought it before it was removed later that day. I have played quite a few hours of it and have very much enjoyed my experience so far with it, so much so that i would already recommend it to anyone who likes creating game.
If you want to see some gameplay of it, i've made a youtube video.
I have put so many hours into little big planet and love these types of games. It is so incredible being able to make stuff in a virtual workspace, you can get lost in there for hours. Do you like these types of games too? I would love to know!
