Never seen Stripes, so I took the phrase, "lighten up" in the commonly understood way.It isn't about the gameplay being light and casual. The line in the movie was uttered by a drill sergeant, for goodness sakes. He was neither light, nor casual. But, he knew that people had to work together.
It is about the players not being personally so tightly wound or concerned that they can admit no change or variation, and are not willing to make room for anyone else.
