I have talked with some of you privately about the way the game is designed relying on the simulation of individual sims to determine outcomes, but the fact that the AI is beyond dumb makes it unplayable and definitely not a simulation of anything.
Someone went into more detail extracting specifics and demonstrating the exact problems here: http://www.rockpapershotgun.com/2013/03/13/simcitys-sims-dont-seem-that-smart-after-all/
As you can see from the clear demonstrations, EA was unable to provide the most basic AI algorithms that any intro computer science class would teach. This is really quite shameful, and not worth of a product that people ask money for. These mechanics are CORE to the game, in fact the entire game is based around them, yet they don't function at the most basic level.
