Lol, I remember playing this game in my young childhood, taking out 30,000$ loans and waited to see how long I could last with such an enormous debt. That was before I knew much about the econeme. I should start it back up again, I'm sure I'd do alot better now that I know how dept works :P. Aside from finantial difficulties, the same two things would happen with two of my rides, for every park I started.
1. I would build a wooden roller coaster that was so big everyone was afraid of it, so I would have to demolish a good design because none of the guests had enough guts.
2. I would add a boat hire with no track, allowing the people to row around the lake freely, and then I would check back five minutes later to find that all the boats got stuck, and the only way to unstick them involved drowning all the guests on it.
Another one of my RCT antics, before I knew how to fire people, I would drown them, instantly causing my average guest number to plumit.
