In addition to its impressive "3D graphics", by 1993's standards, one of the key factors that contributed to Doom's success is its openness to user created content and mods.
Currently working on a new Alice game, the famous Doom and Doom II designer, American McGee, believes that allowing user generated content in games such as LittleBogPlanet is not a new feat as Sony likes to believe.
"New trend? I seem to recall this being a 'trend' back in the Doom days. The only difference now is that someone is trying to monetize it," American McGee exclaimed.
"That's all fine and good, but I think if game products or publishers are relying on 'outside the box' content created by users to drive interest in their titles - then they should find ways of compensating those users for developing added value. That might even inspire the user content communities to step up their game."
