The same way any two sims can marry in the Sims 3
On the sims 3 on the 3DS you can marry someone and on the DS I/LITE you cannot.
Unfortunately you can not marry teens in sims 3. :(
You cannot.
No, your sim can't marry it's computer.
no sorry u can on sims 3
Yes
They sure can.
Yes
Yes, But It Depends On If There Are Any Ghosts!
There isn't a new death in the Sims 3 Pets, other deaths apply (eg: drowning), but no new death was introduced in that expansion.
Finding the death plant on the Sims 3 and keeping it in your inventory will save you from death. If you have on ein your inventory at the time of your death, you can trade it to the grimreeper for your life back. I'm not sure how much more your Sim can live for as death has never came into my sims life.
