Valve Software marketing director Doug Lombardi has told GamesIndustry.biz that consoles must embrace user-created content.
"I would argue that it's the biggest component those guys have to get over if they want online to matter," said Lombardi.
"Half-Life 1 was okay as a multiplayer game and Team Fortress Classic was really good, but Counter-Strike kicked both their asses no question. And that came from a kid going to college in Canada and another kid going to high school in New Jersey, who had our code and thought it would be cool to play our game.
"The PC has that great advantage; has had that great advantage, and it comes from multiplayer and modding starting in the early '90s and [online] multiplayer only showing up on consoles in 2000 or 2001.
