The Old School Renaissance is a microcosm within the RPG world. Although many (including myself) refer to the OSR as a whole, cohesive thing, the reality is that the movement is more the result of at least half a dozen origins that random-walked into game preferences which, to an outsider, look similar. The broad preference towards the genre establishment of Dungeons and Dragons (or at least Appendix N, if not the system itself) bounds the definitions we work with; other retroclones and revivals like Cepheus and RuneQuest aren’t included, even if they too are ‘old school’. No, the main thing that all vectors of the OSR have in common is that they are trying to recreate the time when the roleplaying game was new. And when RPGs were new, either literally or in the eyes of the designer, the new thing that they first touched was (almost always) D&D.

All OSR games are aiming for either D&D as it was, D&D as it could be, or D&D as it was supposed to be. D&D as it was is simple; Old School Essentials is a straight-up retroclone and proves that ‘Basic D&D without shitty layout and shitty editing’ is a winning recipe. It’s the best known and best selling retroclone, but the retroclone camp of the OSR is arguably the oldest (to the degree that OSR is a label we can trace it back to OSRIC). D&D as it could be is where we start getting a lot of the distillations; the rules in early editions were such a mess you barely used any of them, so clearly one could write a game only using those few rules we could actually make work. This is where Into the Odd comes in, this is arguably where The Black Hack comes in, and, if rules were in any way supposed to be primary in the game, this might be where Mork Borg would come in. This example shows setting and tone are a different topic here than ‘game’. D&D as it was supposed to be is a tough one, and there aren’t many games that really aim for this mark. Whitehack is the one that comes to mind for me, taking the length and complexity of the original booklets and turning that into something much more flexible and consistent.
