In fact, I didn't play it for over a decade after starting. By which time I was jaded enough to be baffled by why anyone would want to play it. Classes and levels? THACO? (It was the THACO era.) Armour that makes you dodge rather than, say, reducing damage? Why are people driving Model T Fords?
I'm rather less adamant about that nowadays. But when someone asks how to start on RPGs and some people insist D&D is the only option I can be heard to tut disapprovingly.
