I could remember owning a gamebook back in the 80's, kind of like fighting fantasy but with hand drawn, first person views of a dungeon. Then I found it by accident, I'm not sure anyone here would be old enough to remember it, but the book was called 'Combat Heroes - White Warlord' by Joe Dever.


The first person views looked like this .......




You could play single player with this one book, exploring the small dungeon, or have 2 books, White Warlord and Black Baron which let you play a 2 player combat game.
If your interested in looking at them, the author has allowed them to be downloadable as PDF's at this site .....

It makes me wonder if someone could do something similar, but much more sophisticated on an e-reader today ?
