Gloire by Rattrap Productions is subtitled Swashbuckling Adventure in the Age of Kings and is a set of miniature wargames rules. Gloire is based on the mechanics of Rattrap's previous set of pulp rules .45 Adventure. As it says Gloire is aimed at Swashbuckling games and hence leans more toward the game rather than the simulation end of the spectrum.
I picked up a softcover copy of the rules at Salute for £10 but they are available as a .pdf download from either Rattrap or RPGnow for US$11 along with a few free scenarios, game aids and pre-generated characters. There is also a yahoo discussion group to support the rules.
