Taken from "Different worlds", issue #7 (April/May 1980).
This was food for thought for me some days ago when i read it.
I still don't know if i basically agree with the author or not.
I consider myself kind of a "system snob" person, as the author calls them, but at the same time it's true whay he says-namely, that a good DM would be able to create a wonderful playing experience even using a fantasy heartbreaker system.
But i am particularly fond of his conclusions, that is: go and play (and come to know and make acquaintance with) as many games as you can in your life. That may only benefit you.
