Unless you download a hack, no.
Sure they can. I'm using sims 2 deluxe for PC (original sims 2 and nightlife ep) and mine get married.
In Sims 2, for PC, adults and teens are not able to flirt with each other, kiss, woohoo, etc.
Same sex Sims can have a joined union.
If you are playing the Sims 2 Castaway for PC then you can get married in freeplay and at the end of the story mode. You can't for the other versions.
The only way to get a Sim teen pregnant is to have the Inteen installed.
Sim teenagers (regular or supernatural) can not get married.
If one of the Sims is married, they can't be married to someone else.
Yes there is a Sims 2 for PC, they are working on the Sims 3.
YES YOU CAN!!!! JUST HAVE TO LIKE EACHOTHER 100% AND PROPOSE! ITS THAT SIMPLE!
YES!!!
Well, it depends. You can either use The Sims 2 PC DVD thingy or The Sims 2 Deluxe Addition. I use The Sims 2 PC DVD one and it worked! So, happy gaming!
