It takes me six months to forget exactly how bad hot dogs taste. I occasionally have a good one, but mostly it is a process of thinking, “it cannot be as bad as I remember, even if I said that six months ago.” It is like Hofstadter’s Rule, only for lower quality rather than longer time.
I look forward to games on two-year cycle. Maybe that is how long it takes me get over the last disappointment. When did Warhammer Online come out? How disappointing was that? Hey, the 2011 MMO crop looks promising.
It is easier to meet expectations if you do not set them too high. After everyone tells you to read/play/watch something, it has a lot to live up to, whereas “so bad it’s good” can be enjoyable under that expectation. Perhaps my greatest disappointments have been cases where I thought I had lowered my expectations enough, but people told me that it was okay as long as you went in with low expectations, so I unconsciously raised my expectations about how well it would go. “It’s not as bad as you’ve heard” is dangerous.
Which is to say, look forward to some really bitter posting next year, even though I explicitly know better! My mental hardware is made of meat; I may truly be unable to help myself.
