"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. That 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."
