This should be mandatory reading for anyone curious about older D&D versions - this is specifically about OD&D (Moldvay version, which was my first, yay), but a lot of the mentality transfers to other editions.

It'd be hard to argue that this is a grognard talking about it. The author is Luke Crane, the guy that wrote Burning Wheel - very definitely a narrative-styled system, in many ways a polar opposite of OD&D.

I think the important takeaway here is to treat older D&D versions like a completely different game, rather than just different rules to plop on top of the game you've already been playing.
