Oktoberfest, eating sausage and leather trousers called Lederhose
Oktoberfest started in the 17th century so that is out but I think there is a better than average chance of the other two being in the game, especially the pants since this is Josh we are talking about
I don't like Oktoberfest. And I've never been there, too.
My mother comes from the rural side of Bavaria. Where there are small towns and only villages. And more mountains. North of Munich.
There's a reason why Munich is called "the secret second capital of Germany", because it is very well developed in every aspect.
But I know the countryside, and it is different there, although the development of industry is something every Bavarian is proud of. But also of the nature side.
Maximilian I of Bavaria was a huge driver of the "30 Years' War". He was so stubborn that he did not want any peace, and he drove the war on and on.

Unfortunately, the English-language article is only that short and it doesn't actually show his whole role like the German-language article does.
This war created some kind of "national trauma", even even today, if people say this war's name, there is an undercurrent of fear within this word. It was even worse that just "worse", according to Wikipedia and other sources. The soldiers not just plundered everything, they completely destroyed so many small villages and
emptied the land.
An example would be the "Sacl of Antwerp" , which is also called "The Spanish Fury" :

The social impact of the war must have been horrible :

As a setting for a combat-heavy RPG, this war would be attractive, I guess.
In the next bigger town to the village where my mother was born, there are still underground caverns, of which people speculate that ghey might have held refugees and food during the wars as well.
They are currently explored and restorated, but in the past they were also definitively used for cooling food during the summer months.
