finished basement renovation: man cave or kids playroom?

[CTyankee]

I have to clean out and do some cleanup and some renovation prior to the sale of our small colonial style home in an established neighborhood. I'm wondering if this room would have more appeal going with one way or the other. The neighborhood is mixed, age wise. We have young professionals, middle aged, and elderly (altho they, like us, are slowly downsizing and moving out. I used to think a playroom/den made sense: kids play on another floor from the adults, keeps lots of toys out of the main living areas. But I am seeing how popular man caves seem to be in my own family and wondering if there could be some happy medium, or if one is by far the more appealing to potential buyers.

Anybody here in real estate? Maybe this is a no-brainer and I just don't know it...
