The Isle of Dread
Like an episode of "Lost," The Isle of Dread was confusingly erratic and intriguingly exciting. This game module for the old-school "expert rules" version of Dungeons & Dragons tapped Arthur Conan Doyle's "The Lost World" for ideas. The concept is that your party of adventurers sail out in search of the rumored wealth hidden upon a remote island. When you arrive you discover the island is populated with a bizarro world of fantastical beasts, murderous natives and magical monsters.
The Isle of Dread came with every purchase of the Expert D&D Box Set, so just about everyone that played D&D owned this, but search me if you can find anyone who actually played this module. My cousin and I gave it an abortive attempt once, but mostly all I ever did with it was to glance through, half-heartedly trying to figure out what the overall plot was. I'm not sure there was one though. If anyone can settle that for me, please do.
