So I got Sims3 PLUS University Life for christmas. It includes both the base game and the University Expansion. I haven't opened it yet, in case I might be better taking it back to get just the expasion. Was wondering if anyone knows if its two seperate disks, or if it's one disk, since I already have the base game installed, will it recognise that and not try to install the basegame? Or Will I have the option to no have it install the basegame since I already have it? Any input would be great.
