I find it strange, too. When you give your park so many additions all in a short matter of time, you kind of saturate the market and don't see the kinds of revenue/attendance increases that you'd want as opposed to if you spaced them out (and had some park rennovations/improvements inbetween).
Sometimes I get jealous, then I remember when we got Chiller, Medusa, Nitro, S:UF, KK and El Toro in an 8 year span
Well, technically 9, but Chiller didn't fully open until 1998, sooo....
Long time no see!
