I just bought this game a couple of months ago - really resisted but at this price.... So I'm playing Newcrest at normal and finding it difficult to make friends, let alone romance and family. I've rotated through all my families to make sure they have homes I like, clothing I like, jobs I like, etc. Back to "my" Sim and I finally get her married and a baby. Suddenly, my husband is getting older and I notice most of the NH is getting older. Next thing ya know, I've got nothing but elderly, single Sims. NOOOOOO!
So, found a piece on how to adjust the aging length through adjusting a file. Then got MCCC, turned the aging off and went through the NH and set all my Sims back to their first life stage and adjusted the time a bit so they are different ages within that group. Then I went through each one and got them all married off with families....and don't get to spend enough time with "my" Sim because of this.
So, how I play it now..... I like aging, although I was so sad the first time my sim became an elder in TS3. TS4, however, is so very different. They have free will but apparently they have little will. Unlike TS3, they aren't that interested in meeting others without my intervention. They don't get married. They don't even have children. So, I turn aging off and on as I wander the NH, as well as Willow Creek and Oasis Springs (?), doing for each Sim what they are unable or unwilling to do for themselves. I prefer TS3 but I oddly find the issues with TS4 somewhat challenging and find myself returning to run the circle of all 3 NHs just to keep them moving along, if not in time, at least through deeds. But I do miss my own little simmies and am always stressed that they'll age without me while I'm off doing what this silly version just won't do on it's own!
