www.investopedia.com has a stock exchange simulator. It doesn't run a very complicated system as it takes all the data from the real stock market, using all the figures and values the market contains. This simulator can be used to start understanding and practicing in the stock exchange market as it treats with virtual money. Each user starts with $100.000 and can be invested in any way. It is very reliable as all the values are updated real time but the feel is not the same as the user is not earning or losing any real money.
Simulators can also be used for training methods, such as complex surgery where no mistake can me done so the doctor can see the reactions of the body. An other very common simulator is in the Formula 1 teams, where the drivers practice in a simulator to know better the track. It is much cheaper than practicing with the real car in the real circuit.
There may be some simulators that are not much real as the algorythms may not be very complex so the user will not find it useful but as time is passing by, simulators are getting much complex and the graphics are getting each time more real and at some point in the future they will be even better than real situations, so the users will find it very useful and reliable
