I play computer games, cards, game shows, strategy games like Angry Birds, Facebook's Everwing, a new game for me on Facebook called Thug's Life which is a casino-like game. After years of searching I finally have the original Playstation console to play Tomb Raider based on the movie Tomb Raider. I played this game when my sons were little. I would coach them as they played and of course they showed me a few tricks too.
I used to play Mafia Wars on Facebook. That could be addicting but when I was tempted to spend money on it, I stopped. It was also a huge time-waster.
Funny, but I tell some folks that we meet, that we are very active in sports. "We bowl, play golf, play tennis and ping-pong." Then, I will tell them, "All on our Wii Game in our living room!" They get a kick out of hearing that.
I'm not a player of advanced games. When I had modern internet speeds, I would play trebuchet games and stuff like that. Now I'm in the country, I play backgammon, Scrabble, solitaire, billiards, etc. As others have alluded, those who don't believe in time travel need to play video games for a while.
