Quoting Nintendo Life's feature:
"Playing the Mega Man series is cathartic in many ways. You get to listen to great music, appreciate the impressively cartoony visuals Capcom wrung out of the NES hardware, and experiment with many unique and varied abilities. But overall, we tend to like it because it's mindless. It's a platformer with clear rules and obvious (though difficult) goals. We don't need to think too much.
But that doesn't mean we can't be enriched by the experience. In fact, if you keep your brain switched firmly on as you battle your way through the endless waves of Robot Masters, you're liable to learn a thing or two about the world around.
To help you on this quest of video game-assisted self-discovery, we've compiled a list of ten life lessons we've learned from playing Mega Man."
