Some of us have seen people seeking to back-date their FRP involvement to a point before the actual D&D game appeared on the market. In some cases, I suspect, this a more or less transparent attempt to disavow D&D’s direct influence on them. As such, it tends to fool exactly no one. But in other situations, it represents the way that the world was waiting for D&D, that the time was right for it, and that- when the game appeared – we were prepared.
Did you play D&D before there was D&D?
