In my experience, not to sound overly melodramatic, at the airsoft games that I have been to (there have been some legendary ones) I have rarely come across players who have felt like they have "lost." The afteraction, the bbq, the comraderie and so on... in airsoft everyone wins. Whether it was the great kill you got or the outstanding picture of you that you put on your facebook later. Objectives are met, some aren't. But in airsoft everyone wins. That's why we keep doing it.
In war, everyone loses. And don't make me get into that.
