Its not that your "age group" ruined it, if anything, it is your age groups parents. They are the ones that initate legal action. Most kids don't get fucked up, then go, "I'm SOOOO suing you! You are SOOO sued!" They suck it up, and keep playing busted up or not.
Besides, how long do you have until you turn 18? Is it really a big deal if you have to wait for a few months? See it as a chance to get EVERYTHING you need or want for airsoft, before you actually get started.
