Airsoft is one of many sports that can be classified as extreme. What exactly does that mean? Technically, an extreme sport is anything that exceeds the traditional intensity of a sport. Games like football, although they involve contact, are still relatively structured and are filled with rules and regulations that control the gameplay and ensure that things remain safe. Extreme sports are those where you are placed in crazy situations and it may not be apparent what to do. For example, professional snowboarding is considered extreme because you need to have complete control over your body and what you are doing, and there are dozens of decisions that can be made at any instant. In much the same way, airsoft is above other sports in intensity because of the freedom of movement and the situations you are placed in.
In the game of airsoft, you go up against one or many other people, and try to eliminate them with airsoft guns. These are replica guns that only fire plastic BBs, so although they look close to real and still fire projectiles, they are thousands of times weaker than a real bullet, and getting hit only feels like a small sting. Nonetheless, being in an airsoft game is exhilarating, as you still have both an inherent and a goal-related reason to avoid getting hit, and there are always cool things that could happen in any game. There is no doubt that airsoft is an extreme sport, and can legitimately stand up with all the other extreme games out there.
Airsoft also costs a lot less than other extreme sports. In sports that involve the use of vehicles, you have to drop many hundreds or thousands of dollars for something, while in airsoft, the only somewhat large purchase you need to make is for one or two airsoft guns. It is also necessary to occasionally stock up on more pellets, but those are very cheap, and you can get one thousand BBs for less than the cost of a pack of batteries.
In addition, there are many kinds of airsoft guns, ranging from airsoft sniper rifles to very affordable pistols. This kind of variety ensures that all airsoft games are exciting and as extreme as possible.
