I somewhat have to agree. According to many arguments I've read on the web, D&D seems to many themes with the stereotypical Western movie than anything else. Things like small, isolated towns surrounded by "savages," bandits, or other agents of chaos and a small group of self-sufficient, independent-minded people entering the town to make things right. There are a lot of medieval trappings, magic, fantasy races, and so on, but I'm not sure the fundamental game deviates too much from the standard Western. YMMV, of course.
