I'm not sure what you may be referring to xlom3000. The difficulty is the exact same as the FFIV:A game since... because it's virtually a straight port, translation and all (except for place and character names which use the DS versions, likely because the script of FFIV: After Years.) However it lacks the prevalent bugs found in FFIV:A and is generally a more enjoyable game.
The Auto-Battle feature is a great addition, unlike the one in FFIV DS the battles in this are easy enough to use it sometimes. Not to mention it speeds up battles Immensely, literally the battle speed and even effects speed jump 3x to 4x faster and all you have to do is hit select any time in battle and the character will do the last command issued ad nauseam or if they can't perform it anymore.
The new graphics are nice and the face portraits are Worlds better then that garbage they used in FFIV:A at least in my opinion.
Despite early rumors the Lunar Trails are in the game unscathed, but no new scenes from the DS version sadly enough. A great game and a nice send off to FFIV (It's our job to continue its legacy from this point on, eh?) Interlude is unfortunately very, very, short and some juicy plot points are picked up and dropped abruptly sadly. If you didn't shell out the 40 or so dollars to play AY in its entirety on the Wii this is the best time get it, it even restores the extra Challenge Dungeons that were left out by the conglomeration of Ceodore/Kain/Hooded Man's tale as the entire first chapter of AY.
