Hey again Jenny-TS3!
After firing up the Sims3 a few times, I can
confirm ...
(on a basic, off-the shelf install of the
The Sims3 /
World Adventures /
High-End Loft /
Ambitions, including 505.2 MB of "The Store" items, a clean install install in that order, install date 8.06.2010, )
... that the "Aging" value a player applies on the options screen is Static (and will impact any games played or saved under that state).
Saved files inherit the values invoked by the settings dictated by the user, regardless of their saved location (given the conditions I stated above), each and every time the saved file is opened.
Hope this helps, and you manage to "get" the Sims3 soon!
-- Happytime
