Yes, it needs to be P.C or Mac. The game is 'The Sims 2' Base game.
Here is a link to the Sims 2 Base game for your computer (P.C) you can buy on amazon.com. It's only about 21 dollars USD. You can also buy it anywhere that sells electronics.

If you purchase the Sims 2 and decide you are happy with it, you can then decide to purchase 'expansion packs' which are 'add-ons' to the Sims 2 and provide you with more content and features and expand your gaming experience.
I sound a bit like a commercial- but that's the info.
