Hello,
with crossover Linux 9.2.0 I got this game to work without problem by installing it in a windows xp bottle.
Everything seems to work fine. I have jsut played it for 5 minutes to test it, but I will test it more. Installed with all patches.
How:
create windows xp bottle
install directx modern; activex 10; microsoft net 2.0; microsoft core fonts; internet explorer 7.
afterwards: install the sims 3
after that: download the patches and install them in the xp bottle by using crossover install software.
I don't know if all these ms programs are needed, but it works now.
greets
