I used to play AD&D 1st Edition when I was just a little nard...back in the 80s when the media was telling us Dungeons and Dragons was a gateway drug that lead to suicide...or even worse...DEVIL WORSHIP (cue overly dramatic music)! Anyway, Dungeons and Dragons was owned back then by a British company called TSR. TSR released a series of books called "Endless Quest". Looking back...yes...they were a little cheesy (they even released Dungeons and Dragons romance "Endless Quest" books targeting girls)...but back then, MAN! Were they the absolute shizzy nizzy! I had a whole bookshelf jammed full of them! Each time a new one was released, I had my friendly neighborhood RPG gaming/comic shop order it for me. Two titles that are stuck firmly in my head are Revolt of the Dwarves and Revenge of the Rainbow Dragons. Good stuff! So, I am now 47 years old and hoping to capture some of that old magic from back in the day.
Path of Death and Dungeon stompage sound like the stories for you. Eternal, Necromancer, Death's song, and Rogues are some of the darker side of that old school fantasy stuff. The Last Chieftain is also a solid read. Something that isn't quite on the D&D side of things but is pretty close is "The Price of Freedom: Innocence lost". It's Classical period, no fantasy, but still a good read. Sir Osis is worth a look if you want something absurd, or silly. Or just want to try a game with an incompetent character.
I like the time jump from the '80s ... to "now I am 47 years old."
It sort of does feel like that sometimes, actually.
Had a few of these, though the ones that I played through a lot were:
Dungeon of Dread
The Dragon's Ransom
Lair of the Lich
We had a whole thread on the FF series in the Reading Room forum (Not that anyone reads that area much)
