In Roller Coaster you undertake the role of the ultimate park manager, where you control everything from finances to construction and land development. It is awesome as you can build any ride you want as long as it is in your budget, or if you don't like the rides such as roller coasters that are already built for you, you can create your own. You can play freely or do the missions where you have to complete certain tasks, like creating certain buildings, or making a certain amount of money, or encouraging enough people to come to the park and so on. You can alter all the finances, from entrance fees, to ride fairs and even set up your own advertising the opportunities are endless. The game is pretty simple but it is a bit difficult for youngish players even though that is its traget audience. Relatively ok graphics and a pretty good game all up.
