Now I kinda feel bad for sharing those pics of TS4 Cormac in the What happened in your TS3 game today thread... sorry!
Truth be told, the only reason my sims tend to all look the same is because I have very specific tastes in what I find attractive. Yes, I utilise the sliders and whatnot and my skills in doing so have improved greatly. If you were to compare my first TS3 sim with my latest TS3 sims...
