I agree that modders won't need to go by all the restrictions that EA must commit to. If EA team decided not to focus on "shaving legs", it would not really make a difference whether some EA employee came up with a brilliant shave legs feature. A modder could add that feature without needing to c heck what EA thinks of it. And then there is animation quality etc. Modders do a great job, but I guess some of them might have been ditched if it was an EA supported feature to be added. Personally I find some *not perfect* mods to work wonders with my game, but I base much of my game on imagination. I also can deal with lag without pulling my hear out. Other simmers prefer best possible graphics or zero lag.
Traditionally modders and CC creators were a great deal of the sims series. I think EA has expressed that they appreciate the creative community, meaning they probably see it as a good thing that EA is not covering every single aspect, but leaving tidbits to the modders has become an important side of this game.
