I don't think the people who would be bitter about E:FE are the original Elemental purchasers, since they got a heavily updated and fixed game for free.
Now, if there were people who would be bitter and attack the game without providing *legitimate* criticism of the game, it would have to be the white knight to the rescue of a helpless damsel crowd. There's a lot of angry peeps out there who got it in their mind that Brad W. has a harem of chick slaves under lock and key at his evil, evil giant corporation. And they are the type who would go out of there way to discredit and slime anything associated with Brad W. in any way or forum, since hey, that's what white knights do: SLAY THE DRAGON!
