Okay, let's address this. I can't list every possible thing that has ever existed that has been called "Adventure", especially because most of the things that would have been called "Adventure" in the past would now be categorised as "Fantasy". The term "Fantasy" in the sense we recognise it today, was arguably coined to describe Lord of the Rings and the many works it inspired.
See, the problem is that in the past, we didn't know a lot about the world, and so fantastical things and myths, and real things that happened were basically recorded in the same histories. They were effectively interchangeable. When we talk about Shakespeare in modern day, we categorise "history plays" about real historical characters we have evidence existed, like Henry IV or Richard III differently from plays about mythical ones like King Lear or Hamlet. But to Shakespeare, these were all stories he adapted from history books.
So Journey to the West, that's an example of a pre-industrial "Adventure" story from outside Europe. It's about a journey, it's kind of episodic and they visit all these wonders and have adventures. Except in the modern era, on Tapas, if you adapted that into a comic, you'd probably put it in Fantasy, because it's a journey where three of the characters are magical beings and they keep getting into magical problems. But in the past, stories like The Odyssey, about travelling to "strange lands" where they have strange creatures were all kind of lumped together into one genre because it was pretty hard to check which bits were fact and which bits were fanciful artistic license. Like Unicorns are probably based on accounts from people who travelled to Africa, saw rhinos, came back and said "Ohh, I went to this strange land where there are these creatures like big horses with a horn on their heads and a tail like a lion!". If you believe everything in the Bible is true, for example, as many people did and some still do today, Moses went on a heck of an adventure involving all sorts of strange and mystical things like trees that drop magical food when you need it and bushes lighting on fire spontaneously to talk. There are real things in the story of Moses, like real places, some real historical characters, but also a lot of elements most people would call Fantastical. It's a lot easier now to fact check. We know you can't sail to "The edge of the world" and encounter a dragon, so we can draw a line between a travelogue or a fictionalised autobiography of a person going on a road trip through India and encountering elephants written by somebody based on research they did, and a fanciful account where somebody visits the fictional european country of Latveria ruled over by benevolent dictator and masked sorcerer-scientist Victor Von Doom.
So when people ask, on Tapas, for an Adventure genre, separate from Fantasy, Action, Drama and Mystery, I think it's disingenuous and arguing in bad faith honestly, to pretend not to know what they're asking for just to misrepresent my position on the issue. Especially when most of them cite "Tintin" or old pulp adventure stories as an example of what they're intending.
They are asking for a category for a fictionalised account of a journey in our world in which the most pressing matter the character must deal with is some kind of danger or problem in that "unexplored" or "uncivilised" or "dangerous" land that for whatever reason the native people of that land cannot or will not fix, and where the difficulties along the way are of the dangers, secrets and strange customs of the foreign environment and culture. If the problem the character had to fix was an emotional one, it'd be a drama. If the journey was the backdrop to two people building a relationship, it'd be a Romance/BL/GL, if it was a journey in a fictional magical land, it'd be Fantasy, and if it was to another planet, it'd be Sci-Fi.
So what does that look like in a non-colonial context? Is there a tradition of writing stories, and more appropriately to this conversation, comics, in countries outside of Europe and the US, in which a character from the creator's native country, goes to other real countries to save their native people from a problem that they are ignorant to, while braving the dangers of that untamed and unknown land? Have any of the people asking for an Adventure genre asked because they are just dying to write the story of a strapping young Egyptian guy who comes to England to save King Arthur's sword from an evil druid while he battles dangers like dark wet forests full of sheep ticks or burial mounds haunted by spooky ghosts or markets full of angry football hooligans? This is the issue: The adventure genre is about the thrill of the unknown world, and in the internet age, you can't just make up crap about other countries to make them more excitingly mysterious and dangerous because people from those countries will read it and go "um...what?" It's largely been eclipsed by Fantasy because that's a fictional world that can be unknown and mysterious and dangerous.
