Just for an example, there was a small Muskoka game I attended earlier this summer.
It was a milsim event, and with a fairly low attendance, not much was expected.
But dammit if it wasnt one of the most fun times ive ever had. Most of the day for me was hiking around in the forest with scarecrow well trying to find our way and avoid our enemies. We ended up in only 2 major firefights, most members of the event didnt fire more then 150 rounds, even though the event lasted several hours....
Now , I know for some people, this sounds like the more boring thing in the world, but for some, its the only way to go.
In conclusion, some people can handle keep their finger off the trigger and only the trees for entertainment, some people just cant.
