There are productivity lessons everywhere, if you just look. Here are four lessons I learned from a video game my daughter got me into, "We Bare Bears Match 3 Repairs."
I like matching games, and when my daughter started playing this one (based on one of her favorite cartoons), I peeked over her shoulder. What makes this game different from most is that there is no time pressure - a round is governed by the number of moves that you make. Make less than "par", you win the round. Otherwise you need to try over. It's fun, and it made me think about the general rules I was applying to select my moves...and all can be applied to productivity.
