I-ll post here as well a short and simple how to install sims 3 on ubuntu
i run it under wine version 1.7.27 and have an original copy of the game, not downloaded from origin or steam
you need to create a clean 32bit wineprefix if your pc or laptop is 64bit, then you have to install inside of it the components necessary to run the game you can find a list here

be careful when you install the .NET components ,dotnet40 and dotnet20, to install them follow these instructions

once you-ve done all this you just need to follow the normal process of installation
put in the cd, open it as a folder, click on sims3setup and begin the installation, once it-s finished, run the game once, then download this cumulative patch to update your game
