Yes I had gotten this game as a birthday gift for my husband, but unfortunately he hasn't had much chance to play it. Roller Coaster Tycoon, if you're unfamiliar with it, is a simulation game where you design and build a theme park. Though the roller coasters are an important piece of the game, there are many other rides to build, as well as landscaping and scenery, retail booths, and walkways. There are multiple scenarios that get progressively harder and have differing goals. To keep you from getting ahead of yourself, certain higher level scenarios are only available once you've finished lower level ones.
Goals typically involve meeting certain criteria by a set time.
The criteria are park attendance, park rating, and company value. After my goal had been reached, I usually had a successful smallish park and a lot of money, which makes experimenting easier. Although the game in general is very easy to learn, some specific parts take longer to get the hang of. In particular, it took several tries before I was successful building underground paths and ride elements. Building roller coasters is another challenge - it took me a few complete destructions of my ride in progress and several tweaks before I got it to work right.
