A former Mass Effect developer has some advice for gamers: “Stop thinking you’re a producer.”

Ex-BioWare staffer Christina Norman, now working for League of Legends developer Riot Games, made the remark at the Game Developers Conference in San Francisco following consumer outrage that Mass Effect 3 has day-one downloadable content.

The “From Ashes” DLC has angered some gamers, who believe that if the content is ready to go upon release, it should be included in the game.

However, Norman disagrees. “There's no point in releasing DLC a year after your game has come out when most people have already sold your game back to GameStop three times.”

“That means getting it out early; that means even day-one DLC.”

Gamers need to understand that day-one DLC doesn’t mean the boxed game is lacking, states Norman.

“[Day-one DLC] is a terrible thing to some players. Players rant - they know nothing about this DLC that's coming out except its name. But then it's 'oh this game must be incomplete, the game must be ruined.' Game developers are not evil. (Some are evil.) But most are not evil.

“We just want to release awesome stuff. Players please, give us a chance. Judge our games based on what they are. Judge the DLC based on what it is.

“Stop thinking you're a producer and telling us when and where we should be building our content.”

Consumer anger over the “From Ashes” DLC reached new levels over the weekend when it emerged that some of the DLC’s files appear to be included in the retail disc.

Some consumers are also frustrated by Mass Effect 3’s ending, and have begun a petition, a twitter account and a Facebook group in an attempt to get BioWare to change it.

Mass Effect 3 was released last week for Xbox 360, PC and PlayStation 3.
