Nothing. All of the data from your friend's game is saved on their computer/console hard drive, not on the disc itself. You can use their disk on your computer/console without interfering with your friend's game
Um...you buy it. Or steal it(don't try it). You can always borrow it from a friend and download the game on your own computer though. I hope this helped you!
No. You can only have friends in that game.
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.)
Family friends are simply that, friends of your sims family.
Not in the base game there is one in the sims 3 showtime expansion it's called a sim port( airport) and you can perform in your friends sims. Which has never been on sims before!
Yes but you must have the base game, The Sims 3, to play. In Generations you can have bachelor and bachelorette parties, imaginary friends, and much more!
The original games (of 2 and 3) can do this, you might just need to wait a bit longer for it to happen.
The Sims 2 pets is an expansion pack. To use it you must have the original version of the game. The Sims 2. The Sims 2 Pets does not contain the files needed to run the game. It only is the files to add Pets to your Sims 2 game. unfortunately you are going to have to purchase the Sims 2 also before you can ply your game. if you want to get it cheaper, I would suggest buying it off of eBay You could even borrow it from a friend and install it, because once you install it, you can install Sims 2 Pets and just run the game off the Pets CD.You don't really have to buy the game. Just find some way to get it installed on your computer.Hope this helps!
Infinite.
My first Sims game was the original Sims and then I got Sims Makin' Magic.
Apparently its the Sims 3 - 4 seasons, I hope so anyway, weather!, but i looked on a question and answer interview with one of the producers and he kept putting anything can happen, but that's what everyone is saying. actually, the sims medieval is their next game. It's not an expansion pack off of sims 3 but it is a whole new game by the creators of the sims.
The Sims Online happened in 2002.
