We we take the sport much less seriously than most novices. We are willing to pay $150 for national events because we enjoy meeting other airsofters from around the US and like the size and scope of the game play.
AA is not forcing anyone to pay anything for any game. Big events come and go, but free local games happen all the time. The summer is tough for airsofting because we have to travel to evade the heat.
If you want more games, figure out a scenario, place, date and time and host it on your own, nobody is stopping you.
