Hey, I wonder if Call of Cthulhu could come into this category? Often played as one-shots, in a campaign it is almost always a case of how slowly does your character deteriorate rather than advance!
I've played CoC a few times in campaigns which lasted more than a month of sessions played every week. It certainly wasn't my cup of tea, for the most part. Most of the other players and I got bored after awhile. It's not my first choice of a game, other than maybe as a one-shot.
At that point, I think it would be fair to say, "This is not Advanced Dungeons & Dragons!" Screw calling it "just bad D&D". That simplistically gives a few game mechanics supreme importance, when elements at least as fundamental -- addressed at length in the Dungeon Masters Guide -- have been cast aside.
For the most part.
This particular DM was very anti-"monty haul" and very anti-munchkin/powergamer to the extreme. It doesn't surprise me at all that just about everybody who has ever played his games ended up revolting and dropping him as DM, from being really bored and frustrated. Today I don't even bother returning his phone calls anymore. He only ever phones me when he's looking for players for his games.
