Semi realistic. I love to inject some occult and perhaps other shenanigans but there's usually an overall set of "rules" I follow. I tend to keep the aging on at least for the families I'm playing and I hardly ever use cheats unless it's something simple like offering a certain sim makeover or something. I tend to mix occults in a way which I find immersive. For example: I may grow attached to a certain sim and want to keep them living forever. So I'll turn them vampire because, to me, that is an immersive way to keep them living forever.
