It's rather simple really.
If you're fine with a game that doesn't take the setting "French Revolution" seriously and tries to toss in random ideas that don't even feel like they belong to the same development team. Then you're gonna love it, maybe.
If you're not tho...well...you'll be left wondering, a different version of Ross's thoughts "why aren't there more games set on the French Revolution?" instead as "Why didn't they just made 3 or 4 different games set on the French Revolution if they loved it so much? Why did they shoved it all in one?"
There are games that try to add DLCs later on in order to release unfinished games. This is the part of the text where I make an analogy relating such events to what happens in this game, but I honestly don't know if it's fair or even that simple.
Whenever it was the case of someone using too many hallucinogenics or too little, or if a hacker edited the script and it ended up being better so they just rolled with it, or the producers just had enough of France and it's...attitude, proceeding to throw a big tantrum...may just remain a mystery.
