You can happily download both of these games to your Laptop if that's what you mean, the games are completely separate to each other and there is no reason why they cannot both be on your PC at the same time.
If you mean once you have bought and installed The Sims 4 can you automatically play The Sims 3 then no, you will have to go out and buy the Sims 3 game separate.
No, you don't. You will only need the sims 2 disk four if you wish to re-install the sims 2. To play nightlife you need the sims already installed/the two nightlife disks that came with the game and the serial code. Go to support.ea.com to get information on getting a replecement disk. =]
Duh.
2-4 Players are Playable in Multiplayer Mode.
Unfortunately, this is impossible on sims 3.
the sims 3 takes up about 7 GB it's a lot but the game is a lot of fun
Sims 4 or 3. The sims 2 is a really old one and its graphics and other stuff isnt really good!
Your quistion was looking confusing but now it's not: You don't need all 4 to play the sims 2 pets; only one of them, so if you installed the sims 2 deluxe you don't need another 3 because it won't let you, because it has the sims 2 in it, happened to me when I had the sims 2 and the sims 2 deluxe: I had to uninstall everything just to get it on! You only need one of them, not all of them.
They are 3-4 sim days long.
The Sims 3 have 4 save slots.
No. The Sims 4 does not have open world.
