I came across an article in Video Games Magazine, Feb 1984 talking about an arcade game called Bouncer where you controlled a Bouncer in a bar (via a trackball) and moved around the bar floor and removing undesirable charactors before they bother other bar-going patrons. This company was Entertainment Sciences located in Huntington Beach, CA. This intrigued me so much as to Google the games title and I discovered that someone else had already devoted a whole website to this game and one other game, Turbo Sub created (but never released) from Entertainment Sciences, http://www.turbosub.com.
Check it out. I love stories like this. There is never a shortage of things to discover in this hobby
