Brian Caplan en el manifiesto del jugador de rol:

All you need to RPG are rules and imagination. In purely technological terms, then, RPGs could have arisen thousands of years ago. Imagine how vast our gaming libraries would be today if people started writing RPGs in the time of Socrates. Picture the canon of transcendent classics that library would contain! We can’t undo the oversight of the past. But the gamers of the present can and should make up for lost time.

Habla de ello en un post reciente en el que defiende que los juegos de rol son una idea «behind its time». Dicho de otra forma: algo tan sencillo que resulta inexplicable que no lo inventaran antes.
