Just a quick heads-up

Recently Sims3 and several expansions have become available on Steam(matter of fact that is how I got mine), just to let any players using the Steam version know, but the "Create a World" tool does not work with the Steam version, it will fail to recognize that the game is installed. However once you have registered your games on the mypage.thesims3.com/ site it will become available on the Origin game manager and if you switch to using that instead of Steam to play(warning, you do have to download and install through Origin to do this even if you already have it installed through Steam) then the tool will recognize that you have it and become useable.
