I'm a GM and like for my players to have several interesting encounters when making long road journeys between cities. I especially enjoy when the party has options of how to deal with what they encounter, rather than killing everything that moves. Moral ambiguity is interesting too. I'm not a fan of rolling on a wilderness encounter table and coming up with "4 goblins" or "6 wolves". I know, I know, I can flesh it out myself, but often do not have time to prepare.
So I'm looking for a good resource, and one that is preferably of the dead tree variety. I think Johnn Four's "100 Roadside Encounter Ideas" has a lot of good stuff in it, especially since many of the encounters are (probably) non-combat, but I'd like to see ideas like these fleshed out into a one page per encounter format, or something similar. Pretty much any fantasy RPG system is acceptable. Please help!
To hopefully make my question clearer, I am looking for a pre-made roadside/wilderness encounters (not Encounters) book that I can use in my OSR game. Something more fleshed out than a wandering monster table.
