You just won't want to stop playing this game. Like certain books, you're hooked from the very start of the game. The scenarios are actually  *beatable*, after a few tries you're a third of the way through the game,  but it actually advances in difficulty *at the appropriate moments*, unlike  some other games I know of. Now, the most satisfying part of the game  itself: Custom building your own coasters. There are so many to chose from.  Inverted steel, minecar, single rail, mini steel, wooden, stand up steel,  bobsled, etc. It's so appeasing when you actually see people board your  coaster, then disappointing to see the real life physics algorithim sling  them into oblivion, killing X amount of people. Of course, there really  isn't any violence in the game besides freak accidents. Also, this game  helps develop and sharpen management skills, you can do marketing  campaigns, price setting, goal setting, etc. This game is the very best,  top of the line. Do yourself a favor, it's appropriate for any age and  rather addictive, so go buy it now.
