According to my son I spend more time with the game paused than I do with it running and I need to learn that the faster speeds exist... he's probably right, but I'm an incredible control freak when it comes to my Sims, and sometimes I just have to give them full lives, really, really full lives, for example the mother of the family I'm currently playing (soon to be grandmother) is part up way up her fourth career having maxed three already and she's still got about a week to go until she hits elder, on the other hand her husband got his super spy life time wish ages ago and has been just messing about learning the guitar or smashing space rocks, he's way behind on writing reports but I'm just thinking, never mind you've got a week to go until retirement (I caked him up at her birthday party so they are the same age), just let the reports go hang, go learn enough fishing so your daughter can become an immortal.
I play zoomed in to about one room at a time most of the time and switch between Sims a lot to see if they're doing what I told them or have run off to play in the street, sometimes if they're doing something particularly sweet or cool I just let them get on with it and rein them in later, for example in a legacy like game (basically a legacy with some of the rules adapted to my tastes) I was playing a while back I had a couple of cousins who'd completed their life time wishes early in life and had basically been reduced to being child minders and every single time I left them without actions cued up they would seek each other out and start chatting and sharing secrets in some random corner, it was both adorable and slightly creepy.
I'm not much of a builder, I just don't consider myself good at making nice houses, although every now and then I make one I really like and then many many families will get to live in versions of it. I'm going to try and make an ice house though with the soon to be immortal sculptress, not sure how that's going to go, I guess I'll have to see.
