If you haven't been following perdustin's series at Thoul's Paradise on the first cape-and-sword tabletop roleplaying game, GDW's En Garde! here's a chance to catch up.
The Other Little Brown Book
The Fine Art of Pretending to Fence
The Importance of Status
Clubs and Bawdyhouses
No Friends for the Cardinal's Guard
The Vagaries of War and Fortune
If you've never heard of En Garde! and its approach to roleplaying - which includes some significant differences from the model presented by D&D - or simply want to learn more about the early history of roleplaying games, I strongly recommend giving these a look.
