Despite what the description might say, this is a fairly easy scenario as the plateau has more than enough space for you to build a park that reaches a value of $275,000 by the end of Year 4. Research is straightforward, as you can get everything researched before your time is up, but I would recommend doing Gentle Rides first as it gives you the Observation Tower which is the last of the non-tracked rides you can build, to go with the Ferris Wheel, Enterprise, and Coffee Cups. There's plenty of Roller Coasters already available, so don't go rushing to research them.
