I'm making a park in scenario editor, on the largest map size. I want to add a lot of land to buy, but when I do large areas, the game freezes and turns off. How do I stop this happening?

I've never experienced this (I tend to work with small parks) but you may be hitting some hard-coded limit, or a memory issue with your computer. Have you tried adding the land in smaller sections? Or try running the game in a lower resolution until you've added the land. Even though fifteen years old a large park in this game can tax a modern system.

Huh, that's odd. I'm not sure what would fix that, for ya, bud.

First how much RAM do you have and can you add more. I have the same problem with larger parks, I've got so much stuff on my computer, it eats up all my RAM. I have 12 Gigs of Ram and could use at least another 12 gigs. I can only take off so many programs, because my computer isn't used just for games. I would love to ba able to afford to get a gaming computer with about 4 TB of harddrive space and 36 gigs of RAM, and only put on it RCT3 and maybe one or two more games and that's all. I wouldn't have the problem of crashing then. I say this because my computer only crashes when I make a large park of 175x175 and start putting in a lot of detail. About half way through building the park it starts crashing. The game that is and I find myself back on my desktop.
