Regarding video games, the book "All Out War: The Plot to Destroy Trump" by Ed Klein contains the following passage:

"Valerie says Barack is listless," said the Obama family friend. "He mostly sits in his study in the Kalorama house playing video games. He's behind writing on his memoirs. He isn't terribly enthused about the book right now, and he hasn't done a lick of work on it. He'll take phone calls from show business friends like Bruce Springsteen, Jay-Z, and Tom Hanks, but he refuses to talk politics."
