Also it's not particularly honest to try and depersonalize colonialism as something that must be about entire kingdoms, when what you are describing is just "killing people and taking their stuff" repeated over and over. Colonialism is not just something that only exists at the scale of an Europa Universalis game where you press buttons and a Colonialism happens. It's people who go into places, kill the people and take their land, largely because they think they can since the people they are taking it from aren't fully people from their perspective.
The point is it wasn't going into dungeons and killing orcs for gold. It was about taking whole peoples lands, setting up colonies, exploiting the region for resources, etc. And exploration itself, isn't only about modern colonialism. There are all kinds of myths and legends about exploration that go way, way back. And again, perhaps most importantly, even if everything you said were true: killing orcs in a dungeon has zero impact on the world in terms of colonialism. So it doesn't really matter. My sense is this is almost like an academic muscle that has been flipped into overdrive in the culture. It takes these very informed and complex lenses and applies them to media. And sure if you do that, you may see things you didn't before, but that isn't because reality is being revealed to you but because of the lens you are using.
