Yes.
sims 3 pets plus comes with sims 3 but indvisuly you need sims 3 for all things
You need to have Sims3 installed on your computer in order the be able to use ANY expansion packs.
Sims 3 Pets is an expansion pack for the sims 3. You need the sims 3 to play it. The Sims 3 Pets adds pets to the game, as well as a new town called Appaloosa Plains.
To play any of the Sims games, you MUST have the sims 3 installed. Without The Sims 3, you will not be able to download any other Sims 3 onto your computer or Pc
You need the base game the sims 3 to buy an expansion pack. Your question asks if you need the sims 3 pets? You do not need the sims 3 pets to buy other ep. If you don't have the base game or the sims 3 pets then I recommend you get the sims 3 pets plus because that comes with both.
Same way you play Sims 3
No, the versions on the consoles are stand alone games.
sorta,but you have to have either the sims 3 pets or the sims 3 late night,in the sims 3 pets you can play as a unicorn and in the sims 3 late night you can be a vampire,to play as a unicorn on the sims 3 pets you need to find one and adopt it you can find information on how to do it on websites just look it up,and on the sims 3 late night to play as a vampire you HAVE to get bitten by a vampire look it up for more information hope i helped :)
Yes.
No you do not. you just must have the base game installed.
It is not required; you can play it with the normal controller.
I'm a little confused on your question, but if you mean: when you buy the Sims 3 pets expansion pack do you need the original Sims 3 game? Then yes you need the The sims 3 game to play/ add on and expansion pack. hope this helped :)
