When Mattlab first announced they were essentially going back to the drawing boards, my immediate reaction was happiness. We can now create the game we always wanted to. Atari, instead of doing it yourselves, let us help you.
With this, I'd like to share a definition with you.
tycoon
noun ty·coon \tī-ˈkün\
: a very wealthy and powerful business person
This is essentially the definition of an entrepreneur. When rollercoaster is put before it, you get a very wealthy amusement park business person. Who comes to mind? Walt Disney.
I am suggesting a Campaign overhaul. Many of these ideas are built upon form other posts, so please let me know if your post was the inspiration.
RollerCoaster Tycoon World will have 4 themes. This shows me they're probably going all out with the themes. The Magic Kingdom seems to qualify. They have Americana(Mainstreet.) They have Western(Frontierland.) They have Sci-Fi(Tommorowland.) They have Adventure(Adventureland.) We can essentially create Disney theme parks. But, can we do it in campaign?
Instead of doing different scenarios, you'll start with regions. You will have around 5 plots of land of different sizes. These will be connected by monorail. Each plot can be used for something different. Theme Parks, Waterparks, Zoos, and resorts.
Your Theme Parks will all have income at all times you are in the game. That means if you're in Magic Kingdom, Animal Kingdom will still have money rolling in. Next, all plots will be huge. We don't want this to be a SimCity disaster.
Waterparks will be built around 2 components. Pools and slides. These would only require medium sized plots.
Zoos would work like WaterParks, but with safaris and such.
Resorts would be covered later, I could write another post with them.
This is just a rough draft, but this could work out nicely. This would provide a nice income, and leave you as a true RollerCoaster Tycoon!
