Final Fantasy IV remake, and has found more changes beyond new graphics, new abilities and wacky critters. Specifically, the bosses, which were hard enough to be irritating to RPG neophytes anyway, have had their patterns mucked around with, probably to force FFIV devotees to think for a second. For example, the Antlion now has the ability to counter magical attacks, including summons, in addition to physical attacks.
This should help provide a new experience for people who have played through Final Fantasy IV before. For example, this blogger completed the game once, and will now have an opportunity to experience failure to complete the game.
