In my undergraduate acting classes, we spent most of our time playing theater games.  For the most part, I hated it.  The games didn't seem to help my acting at all.  Further, the games seemed designed primarily to embarrass people, and I felt uncomfortable most of the time.
After graduation, I started teaching my own classes.  And what method was at the top of my list?  Theater games!  But not the same type of games that had made me feel so uncomfortable, and which I had felt had no purpose.  Instead, I tried to use theater games to build up my students, to give them confidence, to turn them into stars.
