I've had a gamepad in my hand quite literally before I could talk. I love video games.  But sadly, I have to agree with you. A lot of the culture around it is infantilizing. Playacting on screen things that should be inspiring people to achieve in the real world. I've just never gotten that about a lot of "nerd culture". Most of it is based around heroism. Heros. An ideal to strive toward. But it seems like the norm is to live through it rather than let it serve as inspiration. The weird thing is that I've never seen it anywhere but the internet. Every gamer I've known has been in great shape. But online the hobby seems dominated by fat neckbeards.
