I love strategy games that really get you thinking. Roller Coaster Tycoon garners many accolades in that it allows you to wear a variety of hats: city planner (as you lay out your park), architect (as you design your  rides), landscape architect (as you grade the terrain and select the  perfect varieties of trees and shrubs), park manager (as you raise and  lower the price of popcorn), and so much more. In addition, Roller Coaster  Tycoon wraps all of this in a layer of camp--imagine finishing the design  of a new coaster, opening it up, children file in, then turn green and  vomit on their way out...oops! too intense! The sounds in the game are  hilarious. It even allows you to select individual children and assign them  names affording you the ability to track their moves. Click on any child  and you can see what he or she is carrying, how much money they've spent  and what their needs are. Do you have enough bathrooms? Enough restaraunts?  Benches? This game is fun! Well worth the low price.
