I play a variety of different saves, but in terms of generations, I have one save where I'm in generation 6 of one family. I don't normally count generations as a measure, but that save is specifically geared toward a rotational version of legacy-style play (by my own rules). In that save I've got my game speed set at 150 (rather than the default 25) and I have custom lifespans that total about 550 days, so it takes me a while to rotate through those families. That's the way I like it, though, for that particular save.
