Since this question is probably the most common response to hearing about teenagers and adults shooting each other with modified Nerf guns, This will be the very first topic I address. Most people respond to the idea of Nerfing with comments like "Aren't you guys a little too old for Nerf guns?" or "Shouldn't you guys be playing Airsoft or Paintball?" However, I believe that Nerf is a completely different experience than Airsoft or Paintball. One notable aspect is that Nerfing is much cheaper than Airsoft or Paintball. Although Paintball and Airsoft do offer a variety of guns, Nerf offers a different
kind of variety: the modification aspect of Nerfing allows for customization of weapons. For instance, one Nerf gun may be modified to shoot one dart very far or seven
darts for a buckshot effect. Multiple guns may even be combined. For instance, a secondary weapon can be integrated into a primary weapon as a backup shot when you reload your primary.
But, in the end, it is really all a matter of preference. If you really want to read a more in-depth article about this, here's an article from NerfHaven.com - Nerf Vs. Paintball
