I'm curious about how those numbers break down by type of game. 3 hours of casual phone gaming, e.g. playing Candy Crush while waiting in line, feels different from 3 hours of sitting in front of dedicated console/computer. It's analogous to saying X% of adults read 3 hours per week, outside of work. Reading hacker news for 3 hours is different from reading US Weekly is different from reading a novel, etc. I'm not passing judgement on any of those activities or saying any aren't worthwhile or whatevs. I'm just saying the broad category of "video games" or "reading" is so vague as to be almost useless. The consumers have different motivations and desires. Sorry if this is addressed in TFA; I only skimmed it. Edit: Also, an opinion question: I play the NY Times crossword puzzle on my phone; would that be considered playing a video game? I wouldn't categorize it that way, but I don't have a logical reason when I really think about it.
