My favourite game is Sims2. It's a simulation game where you can make your own family and decide their life. There are no certain levels as with strategy games. The action is not that exciting since you can decide pretty much by yourself and the game gets boring if you have cheat codes. It's only exciting when something unexpected happens, but that's seldom. The graphics varies, it depends on your computer's graphic card and on the settings of the game. Sound effects are not that bad, but they can get irritating, that's why I have the turned off and I listen to my own music when playing the game.
All in all, I would recommend the game for young people, it's more exciting for them than for the more skillful players.
