The base game is now free. The game is a sandbox life simulator. You make Your Sims and you can build houses for them or use ones already made. You start out with a low amount of money and work your way up.... that is the easiest way of explaining the game.

They have quests you can do like starting with 0 money and trying to make 1 million before you die. Your Sim age and also do die........

It's a lot of fun for story telling and just goofing around in general and also very addicting :D
