One of the most highly anticipated Playstation 3 games this fall is LittleBigPlanet, the unique side-scroller/user created tool game from UK developer Media Molecule. However before the developer was formed members of the team created Rag Doll Kung Fu, a very innovative fighting game that was one of the first third party games to debut on Valve's Steam service.

After Rag Doll Kung Fu was released, the team wanted to do a game that they claimed was going to be "more Portally than Portal... Portal, but with scale factor". In an interview with Kikizo, Media Molecule co-founder Alex Evans states that they approached Valve with their game idea and he claims Valve expressed interest in working with Media Molecule on the proposed game. However, Evans states, "nothing came of that in the end" and they ended up with making LittleBigPlanet at Sony. Valve did go on to develop and release Portal to wide acclaim in 2007 (the game developed by a team brought in by Valve after making the similar student-designed title Narbacular Drop).
