yes you need to install sims 2 before you install sims seasons
no, if you want to install the sims 2 you do not need the sims 1 installed.
Nope. You just need all the Sims 2 discs. So to answer your question, no, the sims 1 is not required in order to play the Sims 2.
if you have The Sims 2 and The sims 2 pets, install the sims 2 first and yes you need all four discs and the game case with the code. Then you can install the sims 2 pets and you will also need the manual for the Sims 2 pets or the game case for the code to install the game.
To install any sims 2 expansion packs you need to have the sims 2 installed. You cant just install sims 2 seasons for example, you need to have the sims 2 installed. It should say that on the box somewhere.
You need to have installed the sims 2, the sims 2 deluxe, or the sims 2 double deluxe, but not all of them. You just need to have the regular sims 2 installed to install and play it.
You just put the disk in and download it, you need the sims 2 installed to play the pets version. Just install it like you did with the sims 2.
You can't, you need the base game to play expansion packs.
No
Yes you must get the sims life stories game to install it
Yes you do, because the Sims 3 Ambitions is an expansion pack, which means it is a feature you install on the game it is made for.
Not sure which Sims you mean, do you mean the original game, Sims 1? You need the first game The Sims installed and then you can install expansion packs. It is recommended by Maxis that you install The Sims first (expansions wont work anyway without it) and Makin Magic last.
