Roller Coaster Tycoon's VERRRY addictive, whether it is played by a kid or by an adult. It's fun, it has cool graphics, easy goals, etc. I spent playing it once for 7 hours that I couldn't even hear my mother telling me to quit playing and eat my dinner. When I went to a friend's house, I brought this game and introduced it to my friends. They were all engrossed and couldn't concentrate on what we should have done and instead, played this game for hours. My biggest mistake was lending the CD to one of my friends and returned it to me a couple of months later.
