I showed up at my first game with camo. They really aren't that expensive. And the current clear G&G and ICS are 2/3 what my first gun cost. Also, very importantly, I had boots on, not sneakers.
Am I a milsim nut? Not by any stretch of the imagination. I've been to maybe 1 milsim in all my years (most due to scheduling and lack of transportion). Otherwise all I get to are skirmishes and themed games. But I can appreciate that others around me have an minimum expectation, and that camo just works better when you're trying to hide.
