I think family time is important, as it was a central part of my childhood. Dh has to be forced, but then it wasn't a major part of his childhood. But I agree that it is the glue that keeps the family together.
In the winter, we don't tend to do much in the way of going out, but in the summer I do like to go to the local country parks and walk round the lakes, feed the ducks etc... We also usually get an annual pass for somewhere like Longleat or Legoland and will visit that several times.
But then I also have times with just me and my girls. Often, I will take my girls out to the cinema on a saturday morning, or if the weather is nice to the swings. DH is less inclined to do such a thing. We also have girlie days, when I go out with my daughters (I have only got daughters) and my mum and that's nice too. We'll go shopping and then soft play or something.
When I was a child, we would have regular board games evenings, and we still get together and do this now, as adults (but usually a curry is involved too!). My family are exceptionally close, but Dh is not close to his at all - he says that they just haven't got anything in common. So it something I do enforce on my poor dh!
