M or F?
F, depends on the game.
M – waste of time. Question arises, isn’t the YWN CR a waste of time? The answer is “no”, because it’s useful – you become a little wiser from everything you read, you gain some more insight into the world and you sometimes pick up useful information. A game is usually completely useless, with no purpose other than to waste time.
Reading the news or editing Wikipedia or writing on the CR are much more useful activities than playing games. I can’t recall the last time I played a computer game. Video games I never touched at all.
