I'm a female, started out playing with families. Nowadays I usually play a single sim until I can't resist the temptation to make a family, play that for a while and then I get bored because I can't bear to have them die or change without me controlling every single aspect of their lives... To begin with I played very straightforward, easy families but then I realised how much of the game content I was missing out on and changed my whole style, so to speak. Now I usually play one sim in different takes on the game, changing her traits around except for one - she's a loner, and I loooove her for it. So I suppose it's only natural that with a game as complex and multifaceted as the Sims you will experience changes in how you play from time to time?
One thing I find interesting though, is that I have little interest in male sims. I just find them incredibly boring, unless they have strong characters and don't look at all generic. I've been wondering if this is because I'm a girl and consequently identify better with female sims, but really I think it has to do with how you can personify female sims a bit more - they have more clothes, hairstyles etc, and maybe the game emphasises certain traits that are more feminine? I don't know, what do you guys think about this?
Either way, I definitely don't feel like I'm playing a virtual dollhouse when I'm simming. I certainly wouldn't be getting up to all the crazy things you can do in Sims if I was. xD
