As I said, I can't say that I run the Testing Cheats "too often" since I almost never start them more than once per game session.
Golly, I'm not at all hopeful that a teen style stuff pack would be to my liking. The style sense at Maxis is rather out in left field, especially the guys' clothing. I was looking through the meshes yesterday and came to the conclusion that Maxis must be staffed exclusively by pimps, nerds, and slobs.
