Pre-game prepping

As well as needing to get set for Friday's game session, a poll and subsequent discussion on the Swords and Wizardry G+ community about how DMs treat time (specifically combat rounds vs. ordinary turns) got me thinking and sent me scurrying to my books. Turns out I've acquired quite a few, mostly in charity shops, but my trusty old Mentzer "Red Box" is there, along with dice and character sheets from over twenty-five years ago. Between then and last Autumn I hadn't roleplayed at all, but I'm making up for it now. "Participating" in medium-low medieval fantasy is great and my current novel (Robin Hobb's "Royal Assassin" from her Farseer trilogy) is also tickling that spot nicely.

What do you turn to for inspiration when preparing your games, whether they are miniatures-based scenarios or rpg sessions?

Now where did I put my copy of Pendragon....?
