I'm playing a campaign that's LotFP plus slot based encumbrance house rules, and I've been disappointed in a lot of hexcrawling rulesets I've seen from the OSR. I particularly don't like Black Hack type usage dice / the Necropraxis overloaded encounter die, and that seems to be where thought has coalesced, with Errant being an example of a game that goes all in on that.
So I was delighted to discover that 1e AD&D has a supplement with workable mechanics for temperature (including wind chill!), foraging, hunting, etc. I need to massage it a little to fit into the LotFP skills system because it comes with its own but on the whole I'm excited that I have a way to go inside hexes and give players meaningful decisions about how they dress, where they camp, etc.
What about y'all, what material have you been reading recently?
I've been on a Castles & Crusades kick lately. It's nice being able to break out all the old modules I grew up with without having to jump through a bunch of hoops to make them play "right." Reading through stuff like Castle Amber, Needle, and Secret on Bone Hill has had my mind racing and giving me a huge push towards running games again. It's been great!
Between that and Sandbox Generator I've been able to put together a mountain of content for my players to poke at as they see fit.
