Well first you make a basement and then you put stairs in it where ever there is a space for example if you where trying to put stairs in your house to the basement you would have to have a huge amount of space and delete 6 squares of floor and but 2 stairs then in the basement you put the stairs where 6th squares are then you have basement stairs.
You can put your own stuff on the sims 3
You can take a video OF the Sims 3, but I do not know what you mean by putting in into the Sims 3.
Sims 2 is not a requirement for Sims 3.
Yes you can. Just click the box icon button and they will disappear.
basically the same as the previous sims expansions you build the main floor or a basement if you choose, add a staircase, make sure you add some flooring first otherwise you can put in a staircase, and just go about it.
Well, put the Sims 3 disc in and then something will pop up that will lead you through the setup.
You can not put your child up for adoption on the Sims 3. Though, that would be cool if you could!
