Haha, nice.
Yea, if you're going for "first", wasn't Ultima Online "first"?
First to use the term MMORPG yes, but there were plenty of MMOs before that like Meridian and Neverwinter, as well as the earier MUDS and online rogue-likes.
But yeah, it doesn't matter what you compare it to. WoW is the most well-know of modern MMOs, regardless of your opinion of it (I personally can't stand the game) so it gets the WoW-clone label. WoW, at the time, was a departure from the SOE-dominated MMO space (EQ and SWG) and led to a whole new level of user-friendly theme-park adventure MMOs. At the time it was pretty unique. Now, due to its success with that, everyone and their left nut's mother is trying to copy them, aside from a few shining gems that never get the recognition they deserve.
