When mine were younger, they were into Dance Dance Revolution for the PS2 and then for the Wi,  (One of them danced so long and stomped so hard that he developed microfractures in the shins of both legs.)  They loved taking all the clean sheets out of the linen closet, putting the dining room chairs about the living room and making tents–like a mini city.  Then they would dress up out of the costume chest and play Aladdin or medieval princesses.  They also loved to have tea parties (the whole family had to play) where each person would wear a funny hat, speak in "British" accents and have funny names.   As they approached 10 yo they would get into card games, like Pounce! or dice games like "Navy".  They also loved doing jigsaw puzzles–we would give up one end of the dining room table and everyone in the family would work on a puzzle (from 1K – 5K pieces) on and off until it was finished.  Sometimes it would take a day or two, and others over a week to complete the puzzle.  Most of my kids suffer from OCD, so puzzles are perfect for that!
