Since I've been discussing how to use Treasure Hunter Adventures material for adventures and campaigns set in the world of Indiana Jones, I thought it would also be interesting to look at the history of the actual Indiana Jones RPGs--one from TSR, and the other from West End Games.
I do have to wonder how a cohesive game based on the D6 System would have been received. That set of rules worked well for the Star Wars RPG, and seems to me like it would have handled pulpy adventures well, too.
Finally, here's a story that begins with the of TSR's version of the game. I'll let the website for the Diana Jones Award tell that story.
