World of JRPG's

• MP regeneration is inherently un-fun. Either waste days, grind overworld mobs or have un-fun encounters where you stun the enemy, steal/regenerate MP each turn and then flee before the enemy can do anything - then stun again.
• Due to MP regen, I believe, they made no effort to thightly design dungeons around MP. In P5R, playing on hard, I always found one of the three MP skull thingies, got booted out of the dungeon or reached the end right when I used up all my MP. In Metaphor, I don't think dungeons like the Skybound Avatar or Dragongod Temple are possible without wasting massive amounts of days or abusing MP regen.
• The class system meant that I only ever used the first three party members. I invested so much into them by the time I got the last charater, using him would nerf my entire party. They basically only existed to generate Hero Leafs. The later members have good classes, but I could always just equip them to the first three.
• Sometimes the game is so slow. Each day, you shower, search the pantry and maybe take a shit. When maxing a character or getting a new one, you unlock a lot of classes at once - all with an unskipable animation and some dialog. Same with Masks and Summons - crafting them is such a hassle, I never used either of the classes.
• Lots of skills are overpowered. Nothing in the game can win against spamming Frozen Fortress Tactic or whatever the skill is called - the ice one that adds a ice weakness to enemies. Even Elegy of the Soul went down long before it casted the one-shot move on hard.

Of course, a lot of things are better too:

• Overworld encounters are great
• Getting a rank up each time you speak with a social link feels so much better
• Actually travelling the world is fun, although the only time you even think about the route is in Brilehaven. Kind of a missed chance.
• The rewind feature came in handy, even though I mostly abused it for stealing in the later game. Press Turn is always so snowball-y that the option is appreciated nonetheless.
• I liked doing everything in a single playthrough. These games are so long, I won't replay them for missing social links and such. I won't for the secret boss either.
• Generating A EXP items with maxed classes is awesome. Usually, I tend to dislike class systems because I feel forced to switch them up and play with un-fun ones just to not waste class exp and get completion bonuses - Xenoblade 3 is one of the biggest offenders. Metaphor completely solved this. However, having to click through that many Hero Leafs is tedious as all hell. Towards the end, you get 3-10 of these with a lot of encounters.

Overall, I'm curious what the Golden Royal Reloaded version does, but I don't think I'll touch it. Everything that makes these games special is just such a drag on a repeated playthrough.
