Pre-orders aren't bad in theory. DLC isn't bad in theory. But the the way the AAA game industry are abusing this, what essentially is a great idea - it's not acceptable.

In this very example, extra missions for this game (a game that hasn't even been released yet so why couldn't it just be included in the finished product?) were being locked away from paying customers because they chose not to preorder the game. Sure, they'll be released as extra DLC whenever but it'll be like £10 a pop. Consumers are being punished for not throwing down their money before the game is released.

This isn't just skins and weapon mods - this is sections of game. Sections of game that are ready to play on the day of release. But only if you are willing to pay up front.
