I played once ages ago when work did one of those 'team building' things at an indoor paintball place. I enjoyed it, but I didn't really know anyone else who played.
The one thing that really struck me is how much I never, ever EVER want to be in any real shooting situation. I got killed. A lot.
I'd have played it again if the opportunity came up. Now... I'm reaching that "hurts to think about doing that" age.
I thought it was amusing... I figured there was probably good reason you'd never want to clean your marker barrel in the dishwasher. Starting with, marker barrels are aluminum, and dishwasher detergents are strongly alkaline, which is not a good combination.
