These days I run LotFP, which I see as a more streamlined, balanced and no-frills version of BECMI. But DCC threatens to dethrone it as the game of choice. I'll probably just mash the two together.
Anyway. In my attempt to Become A Better DM, I've been paying attention to a lot of the rules in the Mentzer edition. Noting stuff down, copying tables, etc. I will compile this and make a little DM screen for myself or something like that. When I next run a game, I will be attempting to follow the rules as closely as possible (at least the rules I like). Not because I think the game would fall apart if I didn't; I've been playing this game for over 20 years and had very few train-wreck campaigns. But I'm interested in seeing how the game is supposed to work as written. A part of me feels like I'm missing out on an untapped source of fun by glossing over the RAW. In other words: You need to master the rules before you can break them.
This blog will be partly made up of this analysis. It'll also be full of crap I make myself that hopefully other people can use.
OR I will make a couple of posts, get bored and forget this place exists. We shall see.
