Every show has surprises.  A surprise for me at PAX 2008 were two MMOs that I didn't even knew existed before arriving at the show and seeing their booths and games on display.  Yes, even an MMO buff such as myself cannot know of each and every MMO in today's marketplace.  Sad, but true.  Alright, I'll give everyone a hint... one of the MMOs has the letter 'a' and 'n' in it.  And no, I am most certainly not referencing W a rh a mmer O n li n e.
