Airsoft is a sport much like paintball. Some of the only differences are that in paintball you shoot balls of paint, and in airsoft you shoot 6mm plastic BB's. Another one is that in paintball you carry around a gun with this huge hopper thing and a big gas tank at the bottom and in airsoft you use clips, and the batteries are inside the gun and not a gas tank that sticks out. Or if u have CO2 that's usually inside the gun also, or the spring if its spring powered. That's why i prefer airsoft, because the guns are more realistic and the ammo is much cheaper. The BB's usually do not break the skin, but you do feel a stinging sensation for about 5 seconds or so. It is also based on the honor system, which means if you get hit, there's no way of the shooter to know that, so you have to admit that you're out.
Just thought it might be useful to mention for people in colder climates.
