28 hours Milsim. I enjoyed it but the younger players all flaked out too early.
I enjoy the Gunman weekend games. Sierra Bravo airsoft do a good two day with Saturday night weekend game too.
I'm never too sure of the story/plot whatever in long games, I just like a prolonged scrap with the other team. A MK IX or two when everyone has wound down and gone to sleep is always amusing. Airsofters never stand stag very well.
