Ordinary RPGs aren't that nerdy anymore. FFVII and FFX brought them into the mainstream, and so they're no longer the sole domain of the nerd. That honour now belongs to MMORPGs, which reward only the most dedicated gamers. Without trying to stereotype too much, to reach a high level in an MMORPG you have to put in a startling amount of time, and most of the people willing to do that have to be at least slightly nerdy.
