I've always referred to FFT as one of my all-time favourite games, and replaying it through The Ivalice Chronicles has definitely solidified its place in my top 3. The music is as brilliant as I remember and I'm much more appreciative of the writing now than when I played the original (at the wee age of ten, mind you). Not quite done playing through TIC yet but I don't anticipate being disappointed by the later chapters based on what I've seen so far. Highly, highly recommend!

Should old fans pick this one up? Yes! Here's why:
+ The English voice acting is pretty good! Especially Delita imo, and Argath's VA knows exactly how to make you hate him. My 10yo self didn't read the original game text in British but my adult self finds their use of posh accents for the nobility and rougher accents for commoners to be a rather nice touch.
+ The roster menu has a built-in job unlock tree that shows you all the requirements for each class, which is a very welcome QoL update. (I don't recall the original PS1 game having it but forgive me if I'm mistaken.)
+ The speed button, by the gods the speed button—an amazing QoL update. As someone that played the original on a PS1 with an ever-diminishing attention span, it's all I'd ever ask for in a remaster.

Should you become a new fan? Yes! Here's why:
+ The writing is brilliant! The story is compelling and timeless, and the tonal consistency really does wonders for pulling you into its vibrant world. Also enhancing it is the prominent use of leitmotif, allowing this story to be a feast for eyes and ears both, which leads me to...
+ The music! The soundtrack does an excellent job of framing the story and setting the mood—so much so that I still remember many of the tunes 20+ years later. The woodwinds are beautifully calming, the strings are haunting, the French horns are bold, and the chiming of the bells is otherworldly. I'd describe this orchestral masterpiece of a soundtrack as simply transcendent.
+ The gameplay is unlike any other turn-based tactical RPG I've played. Each character can change to any job (or class), which drives the primary combat abilities available to that character. After learning abilities from other jobs, you can mix and match combat abilities as well as reaction/support/movement abilities from other classes. A mage that's mastered both black and white magicks? Sure! A bulkily armoured knight given thiefly movement and abilities? Why not? A samurai that can nag your enemies until they join you? Hell yeah. What results is that each of your roster feels like they have their own unique identity that you're building them toward, which gives life to even the generic (non-unique/non-story) characters that still chose to dedicate their lives to your cause.

Didn't intend to make this too long but good gods do I love this game ʕ •ᴥ•ʔ
