Yes you need the original Sims 2 and Sims 3 to play these games.
You do not need the original sims 1 to play the sims 3 world adventures. You need to have the original sims 3 base game to be able to play world adventures.
If it is on a computer you need the original Sims to play it. If it's for a console, you don't have to have the original one.
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.
You can't, you need the base game to play expansion packs.
No. The sims 2 deluxe edition contains the original sims and nightlife. To play the Sims 2 Deason you need: - The original sims 2 OR - The sims 2 holiday edition OR - The sims 2 deluxe. This works for all the expansion and stuff packs. =]
No. For the PS2, The Sims 2 Pets will work without the original The Sims for PS2.
No, because you don't need the sims (first one) to play the sims 2!
yes you can. the sims and the sims 2 are completely different games only sims 2 is like a sequal you can play it on its own.
No, but you can get the original Sims for the Xbox and play it on the 360 (but if I were you I would get The Sims 3 for PC)
no you can't
no :)
no, you only need the sims 3 to play the sims 3 :D
