Paintball is a pretty basic sport. In the years I've been actively participating in the sport I have helped hundreds of people play the sport for the first time. While some understand quite well what they are getting into, many really don't know and I break things down for them. I explain that you need four pieces of gear (a mask, a gun, a tank and a hopper) and then you play the game like tag but just shoot instead of tagging with your hand. While paintball can become infinitely more complicated when you get into details, complex strategy or game variations, it's really a basic, safe game. And since everyone can understand the basics almost intuitively, it's a great game for everyone to try.
