Any RPG game based around fighting opponents (or sneaking around and robbing their "dungeon") and taking their stuff as a reward is inherently and intrinsically colonialist. Recasting the antagonists from orcs to either "bad people" or undead or robots or whatever is just obfuscating the colonialist power relations. This extends to RPG video games as well.

My hand-crafted campaigns started having the adventurers visit people that live there, help them with local trouble as guests, and the "treasure table" was gifts given by the people for whatever they did, combat or puzzle solving or otherwise. Once the players adjusted they started saying it was hard to go back to how weird it was to just break into "ruins" and loot them while intelligent beings still lived there that were being robbed.
