In the process of reading about 4e, I stumbled across the old-school Renaissance and retro-clone stuff. After reading Matthew Finch's A Quick Primer for Old School Gaming, I find myself far more excited about the idea of running 0e than a 4e game.
Unfortunately, most of my Basic and 1e games, back in the day, tended more to hack-n-slash, overdone pseudo-epics rather than the kind of play Matthew Finch describes. As I read the old-school play descriptions, I think—damn!—I never played that game. But I want to.
