True to form.
Before you start your quest, you are God. Not metaphorically, but actually. You get to create any type of land you wish to. You get to "weather" your land, add animals, create valleys, mountains, and whatever else you can think of. God does not believe in money, I guess, so all of the landscaping you desire is free of charge.
You get to place your own Sims into the game, give them fancy homes in nice neighborhoods. This episode is a lot more complex than the previous. You have to bo aware of more things at one time, constantly giving attention to the smallest detail.
I would not recommend this game to someone who doesn't have a lot of time to learn and enjoy this classic. Yes. Learn it. Enjoy it.
