Speaking of Final Fantasy IV, I played a couple of hours into The After Years and then got bored and read ahead a bit and it made me laugh how they took the opportunity to redesign Porom to be sexy now that she's 22, but they mostly left Palom alone. On the left is Palom in TAY, at age 22; on the right is Edward in FF4, age 24:

When Palom goes to buy booze in America, I'm sure he gets shocked looks every time he shows his ID.
Porom now looks nothing like Palom (despite being twins), but rather, a new character altogether:
I'll bet whomever designed her got bonked on the noggin and sent straight to horny jail
So yeah, The After Years isn't getting a pixel remaster, and the PSP version still remains the best one with it looking all good and having the, indeed, very very good Lunar Ruins and that one extra place on Mt. Ordeals, and even that one scene where they explain how exactly Cecil takes a shit while wearing his suit of armor.
(It's an assflap and Kain has a smaller assflap and gets jealous)
