I don't keep up with gaming news enough to be able to approach this in any rational way. However, two massive disappointments for me were/are Blizzard's World of Warcraft and Irrational Games' Freedom Force. FF was simply just boring and too unfocused, and failed to deliver any proper introduction to the game mechanics. WoW was a disappointment because I was loving Warcraft 3 and it's expansion et al, but found WoW to be the most mindnumbingly boring gaming experience of my life. I honestly had more fun playing MapleStory. To me, WoW ruined a great franchise, but I can hardly call it a flop, seeing as it's the biggest game today.
