There are a few other Swashbuckling games that may be of interest to the 7th Sea enthusiast. So here are the ones I've found that have helped me in running my campaign.

Flashing Blades (Fantasy Games Unlimited)
Written by Mark Pettigrew

This game is of great use to anyone wanting to run a Montaigne campaign. It is set in the age of the Sun King in France. Players take the role of all manner of characters, from Musketeers to bankers. The system for careers are very well organised and one of the goals is to rise high in your profession, as well as defeat Cardinals and woo rich mistresses. There is a lot of historical detail in the game, as unlike Théah Flashing Blades is set specifically in Historical France. It therefore has none of the fantasy elements of 7th Sea.

Lace & Steel (The Australian Games Group (TAGG) & Pharos Press)
Written by Paul Kidd

Lace and Steel is one of those games that never stays in print for very long. I can't understand why as it is a very good game, rich in background and with a very flowing rules system. The rules are card based, which can be annoying, but has an excellent system for social as well as physical combat. The world is compleately new, a land called Mittelmarch. This place is essentially a fantasy world that has now progressed to the 17th centuary. Magic and sorcery have a similar theme to 7th sea, and you may even wish to add some of the new races. However, good luck in finding a copy. It was originally published by TAGG, but went out of print. Luckily TAGG eventually rprinted it, and a supplement, but finally disolved soon after. The rights were sold to Pharos press, (who had just lost Nobilis to Hogshead) who produced a new edition before disappearing themselves. However, keep an eye out for it as it is worth the search.

GURPS (Steve Jackson Games)

GURPS is one of those systems people seem to love or hate. Personally, I love it. Don't be put off by the huge rulebook. Yes, it does have a lot of rules, but that is so you have something to use for any situation, it is up to you to decide whether to use them or not. Things like magic can be rather generic, but hey, take a look at what the game is called. The joy of GURPS is that you can easily use their Worldbooks in any game, whether you play GURPS or not. They are choc full of detail and setting, because all the rules are in one book. As there are well over 200 Worldbooks in print, I spotted a few that are useful to the 7th sea gamer.
