How bad does a game have to be to make the people that were so hyped up about it actively regret their hype?

Worse than Spacebase DF9, worse than any Final Fantasy game, worse than Aliens: Colonial Marines, worse even than any Battlefield or Call of Duty game.  Those still have plenty of hype-blinded apologists.  WH40k EC has devestated people who used to be hyped and now deeply regret ever wanting the game.  That's a complete about-face in opinion that you only achieve when you _Fuck Up_ TM.
