In person RPGs, tabletop wargames and boardgames are amazing for geek culture. Thanks to local Discord groups, I have an active nerd community that I play games with at least once a week. This has revolutionized by social life!

There is a introverted crafty side of painting and 3D printing miniatures that works great for me too.

These games all work as essentially offline alternatives to videogames and are way more fun!

Also, my local game store serves beer; so its essentially a nerd bar even though most people don't drink.
