I used to love designing complete death traps and waiting for someone to ride it :-p
I remember for one of the challenges I had to have a certain amount of money (forget how much) a certain park rating, and 1000 customers in the park at a specific date. My cousin and I were doing it, and we were kicking @$$. 5-star park rating and WAY over the cash minimum! The final month begins, and we're almost at the 1000-guest number, (at about 950). about 3 weeks later, we're at 990. Last couple days were AGONIZING, as we had spent quite a bit of our cash to get the extra customers, so we had to spend wisely since we had no time to make it back. The number quite literally teetered between 999 and 1000 for the last few days (it didn't go to a single other number).
We failed.......
So, in happier news, does anyone know where I can DL this game now??XD
