yes but you need to go to store and buy it
You cant, you must have an original sims game to install a expansion pack.
no, you do not need your Sims 3 disk, but you will need the disk for the expansion pack you want to install.
As it so happens yes. Hence SIMS 3 EXPANSION pack. Install it exactly how you installed sims 3.
all you need is the expansion, first you install it and then every time you want to play the game you put in the latest expansion disc you installed
The sims 2 pets(but i am pretty sure that you can become a teacher in every expansion pack)
No because sims 2 freetime is an expansion pack.
no. no.
If you are talking about installing a Sims 2 expansion to the Sims 1, it is impossible. You can only install the Sims 2 expansion packs into the Sims 2, not The Sims 1 or 3.
If by "other games" you mean the expansion packs, then yes. In order to install the expansion packs (Sims 2 University, etc.) you need to have Sims 2 already installed. If you don't want to spend money on that game as well as the expansion pack, find a friend who has the Sims 2 discs, and borrow them. Install the game and then install your expansion pack right afterward. That way, you don't need the regular Sims 2 disc to play with your expansion pack. You just have to have the disc for the expansion pack you installed. (However, if you ever have to uninstall the game, you'll need to borrow Sims 2 again to reinstall it.)
No, Pets it's a separate expansion pack.
If you have a Mac, You can install all the expansion packs and only need the last CD that you installed to run the game.
You don't have to install anything because its on playstation2 :)
