I have bias though as a war gamer, I mean we used Greyhawk as a war game map, making up chits, and battling it out between the various Kingdoms too; I mean there was almost no separation between the two for us back then.It's also 1977, and quite likely influenced by D&D in the market.
But, yeah, it borders on RPGs...
