I played paintball with my team from work. I have to say it was pretty fun. It was pretty tiring, and pretty intense, but overall I really liked the action and the strategy that was involved. The only thing that really needed to be improved was the fact that my mask kept fogging up making you blind on the field (you are not allowed to take off your mask during play). If you could just make sure your mask didn't fog, you would have a huge advantage.
Now that I'm home and got to shower up one thing really sticks out, all the bruises I got. Everywhere where I got shot there is a pretty sizable and dark bruise. Since I don't play very often (or ever) I don't have the gear that most people probably have to prevent such bruises.
All in all, even with the bruises, I would still go play again.
