Something to remember is that the sims 2 was created almost exclusively by EA, they had bought maxis lock stock and barrel before the sims2 was released. The still kept the maxis logo though, google for EA buys maxis. You will find a wiki with all the info.
Back to the original topic, its been many months since that conversation I had and it looks like the guy I talked with was sort of on track, there is more CAS customization continually coming out. Some of the things recently introduced have been CAW and tats and other stuff. It is probably going to take at least another full year (Fall 2011) before we really start to see a "clean game". What I mean by that is a game that works how its supposed to work, without a zillion bugs. It was the same way with the sims1 and 2 .. with sims 2 it was not until around EP4 that we started to see the kinks ironing out. I have not played in a while but might fire up a new game after the mods have been updated to work with the newest patch... just to see what sorts of game changes there have been. Also I am quite surprised at how many replies this thread has received and that it is still a hot topic!
