This is another horror bundle featuring Ghastly Affair, the "Gothic Game of Romantic Horror in the fevered age of Marie-Antoinette and Napoleon."

This one is quite interesting, although it does have its origins in systems that put numbers on everything - I'm a little boggled that these include stats for Death and for Lucifer. it's primarily focused on Gothic horror, but claims a lot of other things as inspiration including
Buffy the Vampire Slayer, Supernatural, etc. - a list of fictional characters that might be inspirational puts Faith Lehane immediately after Captain Kronos: Vampire Hunter. It has quite a lot about weird science and weirder magic, horrible illnesses (including several that often get overlooked in RPGs, such as rabies), and period architecture - the last is there because a major theme of Gothic horror was strange crumbling manors and their denizens. While the military history of the era is mentioned in the timeline, it's mostly there as background, and this isn't the game you want if you want to re-enact
Sharpe or
Master and Commander. On the other hand, it would work very well for ideas like a Napoleonic-era version of
The Beguiled and other war-adjacent dramas.
The bottom line is that you get a huge amount very cheaply, and it's full of ideas that could be useful for any game or fiction with similar themes. This is one I definitely recommend, but I should really add a disclaimer that I sometimes forget - I get to download this stuff free, if you don't your mileage may vary.
