Why Modern Beats Fantasy

The editors at Big Download seem to think that modern settings are a better fit for RPGs and MMOs, though they seem to be applying the argument only to high, D&D-style fantasy. Chew on this and see if you agree:
In general, plotlines for fantasy stories too frequently revolve around the opposition of a dictatorship, with the protagonist being a lowly serf or equally low-ranking member of a caste-driven society. But even if the end of the game brings about the promotion of the hero to kingly status, it's merely replacing one figurehead for another. There is little to no social change to be found in these stories. You can never have a story in which a team of peasants overthrows a king by sheer force of arms -- the social organization doesn't permit it. At best, that group would then put their own king in place, but the monarchy would still exist, and someone would still have to be a serf.

The modern urban setting, on the other hand, offers a vast wealth of options for resolution. Rather than a setting wherein a character's range of freedom is limited by his cultural status, a modern hero can belong to any group and enjoy any level of social standing, both imposed from without and contained within. Modern society makes it significantly more easy on the individual to grasp the reins of power than ever before in history. When one isn't bound by the strictures of caste, then one is free to move about with relative impunity, having adventures equal only to their degree of comfort with taking risks.

You might use the fantasy genre as an excuse to be able to have monsters as opponents in your game. But there never have been monsters in history, so that doesn't work as a valid reason for their inclusion. There's absolutely no reason we can't use monsters in the modern setting; it's just a matter of writing a semi-plausible origin. In fact, there is nothing keeping us from having any of the traditionally fantasy-defining tropes in a modern game setting. Swords are still around. Magic is nothing but technology you don't understand. Caste-based organizations are alive and well. What's left to fantasy that requires its use?
