A bit late to the party, but I have to say, the whole thing with Guild Wars 2 was a bit hilarious.
Before release, during testing:
"Oh man, this game is fun!"
"Yeah, it's definitely better than <insert MMO here>"
"So much going for it. I can't wait until it's actually released!"
After release
"HOLY FUCK THIS GAME SUCKS!"
"YEAH, <insert same MMO here> WAS SO MUCH BETTER!"
"BAWWW MORE SHITTY GAMES NO ONE EVER RELEASES ANYTHING GOOD ANYMORE BAWWWW!"
Fickle gamers... you amuse me :3
