[Emperor's Child]

In another hobby area I paint miniatures, and I've found that most younger people don't have the patience for competitive painting... Some of the best results take many small steps, and I felt that what I lacked in raw talent I made up for in approach and determination.

I think that turn based games, especially complex ones, appeal to the more mature crowd for the same reason: Older folks are more patient and prefer to chew on things for a while.
