Game systems may be the most social high-tech development of recent decades. Though you can play most games alone or one-on-one, many center on group participation and a more-the-merrier design. Families once gathered around a radio for family entertainment, later sharing TV movies on what used to be family night Fridays or Sundays, and early game systems and games like Pong and Atari had families coming together around technology, too.
An advantage to some of the high-tech offerings today is that many involve physical activity or fitness, while getting to see dad shake his groove thing, for example, and other games pit members of the same family against each other, creating healthy competition and a reason to keep playing.
Some high-tech gaming is actually old-school, low-tech with a twist, as when an uncle in Europe can play chess with a nephew in Florida, for instance, all online. Joining a fantasy sports league is another way to connect family across the house or across the globe while still playing in the same game, whether on opposing teams or not.
