No, but you can paint your own custom paintings in the art gallery and take it to your room if you like it enough.
nope, not on the DS version.
no, you can't get married on the DS version
There will most likely be a DS version of Sims 3, but it won't be anything like the PC version.
no, your sims can not have children on the DS version of the sims 2. you have to have the gba gameboy version of sims 2 as well in order to unlock the have babies option: have both games in their slots and turn on your ds. it should then unlock the option on your ds game.
In the Nintendo ds version you cant kill your Sim.
no, your sims can't get married and they can't have kids on the DS version. it sucks, i wish you could.
it's unknown at the moment. there might not even be a version of the sims 3 for the ds
As of June 2015, there have been no plans announced for The Sims 4 to be released on the Nintendo DS. The Sims 3 DS version was released over a year after the PC game, so it is likely there will be a version of The Sims 4 released on DS at some point.
no, you can't get married and you can not have any children for the DS version
No. The main goal in Sims 2 for DS is to maintain a hotel, but you can add furniture to the hotel rooms.
There are so many more things you can do on PC on 3DS you can't really interact and the graphics are poor. With Pc you can start familys build houses control there lives etc. PLUS THE GRAPHICA ARE AMAZING! i extremely recommend the PC version ;)
it is currently unknown, but i would expect to see a version of the sims 3 for the ds in a little while.
