Very dependent on which visitor at that age.
DD2 and her less mature DF still played schools, sometimes with every build a bear and similar size doll as pupils, often DD2 actually teaching her DF.
Many of her friends, Hama beads, making buns, cooperative Wii and CD games, disappearing to room and doing I know not what, trampolining.
With her top table partner in crime playing SIMs and being proto teens.
And with her very shy DF, I have no idea, except they have been very close since before they were two years old and met at nursery. (shy DF wouldn't talk to adults without looking like a startled rabbit)
DD2 wants to teach at primary, and subconsciously when little and I thing almost deliberately when older, she works out what to do for hear and her DF to have fun.
DD1 doesn't do this at all, she has play dates with the DCs who are on her slightly wild eccentric wavelength only. Attempts at having my friends DD over were hard work at 10 and hopeless at 13 (DD1 wants to trampoline, race about having water fights, climb trees, chatter about Dr.Who, science and mess about being hunger games charecters and be a big 10yo forever. DDs DD wants to be a teen. It doesn't work.)
