I just finished my playthrough of this hack as well as FF6: TWUE, and I must say that it was a fantastic experience all around. Looking back on the dialogue of the original SNES release after doing so, it's genuinely alarming how stunted and almost robotic the original dialogue feels, even putting aside the censorship of things like death, religion, alcohol, and so on. The new script is absolutely fantastic all around, and I don't have a single negative thing to say about any of it.
Above all, I wish that there was a version of this patch that didn't have all of the various buffs and additions that Project II added, such as...
...and so on. I can understand the hidden passages in caves and dungeons still being highlighted, as ff4kster does not have the ability to edit the appearances of individual tiles, which is a great shame, and I wish that they could be properly hidden. (Speaking of, has the issue with the Sylvan Cave/Eidolon Passage damage tiles not making a sound been fixed yet?) Putting that aside, I always wished that there was a hack of SNES FF4 that was essentially just the Japanese version with an improved and modernized English script, and while J2Evisceration was a step in the right direction, it still misses marks, such as completely excising Kain's backstory about his father in Baron Castle, and having excessive use of capitalization, ellipses, and exclamation points in places where they do not belong.
This hack is extremely good, and I would still without a doubt consider it the definitive way to play FF4. The restored maps (love the Developer's Room!), graphics, monster stats, weapons, items, chest contents, and dummied out character abilities as well as the various bugfixes are nothing short of spectacular, and I supremely wish that my dream of a version of Namingway Edition with gameplay and appearance that is 100% faithful to the Japanese FF4 will ever come to be, but I still highly applaud all of the effort that went into this regardless, as with FF6: TWUE. Thank you!
