I haven't played a Sims game for around 7 years now, and I never really had any interest in them after that, but the $1 sale for The Sims 3: World Adventures and The Sims 3: Ambitions have piqued my interest a fair amount. Which Sims game on the iPhone would be the best for someone looking for something fun with not so much micromanagement? And the best one for a total noob? Would The Sims 3 be worth risking $7 on?
World Adventure and Ambition are boring. I'd suggest getting Sims 3 if you're planning on getting one of them.
The sims 3 is just a limited version of both Adventures and Ambitions. I'd say go for Ambitions as it's the only one where you can build your own house. It gives a bit more play time. Also get kids on it!
