I'm not much of a KIC enthusiast. I've never even met Dane, Boddah, or The Interpreter.
Actual (slightly mushy) answer: I don't know. I know enough random KI ride trivia to make my non-coastering friends' eyes roll, but I don't get psyched every time I go to the park like I used to. I still love the park very much, but it's become less of "this is the best mini-vacation ever" and more of a place where I can relax and get away with each trip. I've come nowhere near the 18-ish visits I made in 2008 in this year or last, but I feel like I've learned to appreciate the place in a new way. (I guess that's one thing that can be said for the removal of The Crypt for me: I never really noticed this until this year. Once upon a time, riding it and Son of Beast were the meat and potatoes of a KI trip for me and my friends.)
If you told me a year, I probably couldn't tell you with much certainty (unless we're talking the late 90's, 2000's, and whatever you want to call this decade) what rides came or went, but I can point out several places in the park where I've had fun experiences since I started buying my own passes four years ago. More times than not, the fun we've had was because we were at Kings Island.
Summarized: I love the place, but not for any particular reason related to what's there, haha.
EDIT: Except for Adventure Express.
