Syl, of the Raging Monkeys blog, made a pretty interesting post about all the ways World of Warcraft changed her. I haven't played World of Warcraft nearly as much as her (it was just a brief stint during Vanilla then a few months later during Burning Crusade) but it made me think about all the ways MMORPGs over the years changed my tastes and expectations in terms of gaming. So, this is my list of those and the MMORPGs who influenced the most on that.
Oh, for convenience, I will just copy the format of her post. :p
