Man, that combat table! Kill me!
I think I have a copy of that. Isn't it like a regular sized hardcover book? Not like a big rulebook? More like a novel or something.The first half or so is actually pretty interesting, about the roots of roleplaying games in fiction and such, and then bits on building a believable world. Then you get to the rules, which are terrible. Maybe I'm thinking of another book, mine didn't have a dustcover.
Those covers more then make up for that table. That game needs to be framed.
I have two of the adventures in the original softcover, and I have to say they are fairly rockin'. One is set in the dead body of a god, and the other involves capturing a fortress, which has some nicely mythic material in it as well.
I have run some of the adventures from both the book Adventures in High Fantasy, as well as Fortress Ellendar and Goldchester. Those were all converted from the High Fantasy system to AD&D1E - it was a pretty easy conversion, if I recall, but the adventures themselves were well worth the effort.
Play through the solo adventure in the rule book sometime. It's probably the best one ever written.
