"If a game comes out and it's not what the players believed it was going to be, what they think they deserve, what they were promised -- the amount of rage associated with that is kind of frightening, to be honest."
Where do players get these crazy ideas from?
For example, imagine that a hypothetical producer was out making comments about how some equivalent for gameplay-effecting items in the real money item shop will be available through in-game means. Why would someone reading that statement be surprised if, less than six months post-launch, the game announces plans for a paid "expansion" that is no larger than the content patches that all of the other games on the market include in their monthly fees? No one promised that new content would be included in the monthly fee, regardless of whether or not it looks suspiciously like "content that didn't get finished in time for the game's full priced retail launch".
Besides, it's not like trust matters in the MMORPG marketplace or anything.
