I too have reservations about TS3. I was so looking forward to the ability to custom create clothing only to find out that there was limitations to the "Mix and Match". I have been able to "customize" clothing but each new EP has made it harder to do so without messing up the file. I mean you have lots of optons in TS2 but these don't go deep enough. Examples: If I create a male sim and don't like the tie on his suit, I should be allowed to change it or even have him go without. If I create a female and think that her dress would look better with a different shade of hose (or none at all) then I should be able to do that as well. Also if I want my sims to be in various states of undress (loosened tie on the male sim or walking in stockinged feet for the female sim, et cetera) then I should be able to do that as well. All without having to use a photo editor. That's what all of the previews led me (as well as others) to beileve about TS2. Tha was just a small portion of what I was disappointed about TS2.
Don't get me wrong, I like TS2 a lot! It's just that I really am not in the mood to be fooled again. I just hope that EA/Maxis doesn't show preview trailers that just aren't real.
