Publisher blurb (introduction by the author, David Morgan-Mar):
Many years ago, when the only role-playing game I knew about was Dungeons & Dragons, I decided a simpler game was a good idea. So I wrote this, with a pen and a single sheet of note-paper, fitting all the rules on one side of the page. I actually played this game several times with my brother and some friends, and we had a great time.
Then the Internet came along, and I wanted "cool" stuff to post to the newsgroup rec.games.frp (as it was back before it split it several subcategories). So I dug out my old sheet of paper and typed this in. I still hadn't noticed that my acronym should have been "OPGIS" and not "OPIGS".
Unfortunately, as soon as anything gets on the net, it takes on a life of its own. Soon someone had written an expansion set: OPIGS Supers!
Many years later, when my original hand-written OPIGS rule sheet had been lost, and for some reason I was reminiscing, I happened to enter a web search for "OPIGS". Lo and behold... it was still out there, on several web sites, preserved forever!
Now, finally, I have decided to take a copy of one of those web pages and host it on my own web site, with this explanation of the history behind the game.
