Hill Cantons blog. Just in case you should've missed it. I think it's an important pierce of news, so sorry if you've already read this! Also this piece of news is (according to Hill Cantons) from the author of Flashing Blades himself, Mark Pettigrew.
"FGU already agrees that I [Mark Pettigrew] own the rights to Flashing Blades [this development is possibly a result of FGU's losing a case against the original authors of Villains & Vigilantes, which FGU was selling without the authors' consent, and without giving them any royalties!]. I'm even receiving (very small) royalties cheques again, after a 20-some year hiatus. I think I mentioned this before, but again, all of you are free to write, publish, etc. whatever you want for Flashing Blades without worrying about copyright. I'm happy that people are still enjoying the game."
Although it is centred on 17th century France, Flashing Blades is also a rules set I would recommend for running a Renaissance game, on top of LotFP (for a gloomer campaign setting), Renaissance (for a more realistic set of rules), and Monsters & Magic (my personal favourite at the moment).
