Two weeks ago, Cryptic announced plans to charge for Champions Online patch content that sounded suspiciously like "sorely needed content that wasn't finished in time for retail launch" (September 2009). Yesterday, they reversed this decision.
As Syp points out that we've seen this kind of reversal of unpopular decisions in the past. The example that stands out in my mind was a pre-release interview in which EA suggested that Warhammer might be worthy of a monthly fee higher than $15. The market apparently wasn't prepared to tolerate a game that appeared so similar to WoW coming in at a higher monthly fee than WoW. Likewise, Cryptic seems to have learned that the market is not yet prepared to tolerate paying for missing content so soon after a game launch.
Though I get Syp's point about giving companies the benefit of the doubt as they try to change for the better, I don't see that much cause for celebration here. Imagine that you went to the movies and, 2/3 of the way through the film, the theater manager comes out and says that the ending of the film wasn't included in your ticket price. Is anyone really supposed to feel better about going back to that theater if they later decide that they are going to show the ending of the movie anyway because they care about their customers? Cryptic announced plans to charge more because it intended to charge more, and there should be no doubt that it will make the attempt again in the coming months.
More to the point, it appears that there is no reason for companies who are considering higher and/or additional fees NOT to engage in this sort of brinkmanship in the future. People who choose not to forgive Cryptic for even making the threat would not have paid the additional fees in any case. In short, we can expect many more of this type of incident until someone finally succeeds in moving market expectations to the point where they can get away with it.
