For Fun and Games, Bare is Best

Hitting anything with a longbow is pretty tricky, not surprising since it is basically a length of bent wood and a piece of string. So when you do hit the target, you really get a sense of achievement. At the other extreme we have the modern recurve and compound bows with their sights, stabilizers and release aids. In the hands of a decent archer, their accuracy is phenomenal. When it comes to playing archery games, their accuracy becomes a bit of a problem in that most games would be over very quickly. For games to be fun and competitive, a degree of randomness is required which these shooting aids take away. Now I'm not against modern archery, its just that it is geared towards one thing - accurately hitting a FITA target.

Removing all these aids  - shooting barebow - means you have to shoot intuitively in order to hit the target. By intuitively, I mean that you look at the target, draw and shoot - the eye and brain guides the shooting arm without you thinking about it. It is similar to throwing a stone at a tin can. You don't aim as such but simply focus on the can and throw the stone. With (lots of) practice, what you see is what you hit. Some of the games have targets at different distances which means you need to rely on binocular vision to judge the distances. Shooting indirect is also a common technique  - shooting the arrow high into the air to that it lands near the target.
So, if you try out any of these games, I recommend you play them barebow style.
