I've only played once in the US, and it ended not too well. It's related to the above. My site is The Mall, which doesn't do the Bang or surrender rule. The US site did. A guy came up behind me, and said bang at me. I promptly shot him and continued on. (A marshal saw and explained my error to me, and I took the hit.) The guy was so pissed (My burst caught him across the neck I think, ouch) that he and his team hunted me for the rest of the day... It was kind of fun, as they had tons of gear and made a lot of noise, where as I didn't, and I was able to constantly move around them, and even ambush them, much to their annoyance. Fun times
