Yes you can install Sims 3 on a PC or a Mac.
ON THE IPHONE/IPOD: Yes, Ambitions is NOT an add on. You don't first need Sims 3 in order to play Sims 3 Ambitions. However, the two games can exchange data if you do have both. ON PC/MAC: I believe that Sims Ambitions does require Sims 3 for PC/Mac as it is an expansion pack. However I do not have the PC/Mac version so I am unsure.
The Sims Medieval is for PC and MAc. So, it is already out.
