What is the best simulation game

It has to be The Sims But thats pretty obvious.Simcity 3000 they ruined Simcity 4 with the auto road thing.Trainz 2009 world builder edition is fairly fun ,it is a true simulation.Roller Coaster Tycoon 3.Simcity Societies was ok more eye candy kinda cool.Soon to be released CitiesXL looks good.Spore also could be good.
