yes you can get married in the sims one two three four and hopefully the sims 5
Yes .When two of yours sims are 100 relantionship then one of them can propose to the other.

No, Sims Pets is only one disc.
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.
no, the sims 3 is still only one player like the sims 2. Edit, Sims 2 was two players
No, it is only for one.
You need the orignal sims 2 disc!
