8.5/10 for me.
Overall a great game but held back by its awful pacing. Every palace took me roughly 3 hours plus a little Mementos here and there so in the end the game is made up of about 25% combat and 75% talking. It's even worse when you've already maxed your social stats before the summer break is over and all you're left with is meeting with confidants between palaces.
Morgana is pissing me off when he decides that I can't go out anymore or worse that I have to sleep immediately. Just ask me if I want to save (which happens a few times during the final) and then skip either straight to Joker lying in bed or to the next morning.
Choices in this game are absolutely pointless or rather nonexistent. They probably only exist so your controller doesn't disconnect due to not being used for 15 minutes.
As far as recent JRPGs go, I had more fun with Yakuza Like a Dragon and Dragon Quest XI S
Yup, that's a big problem. It's more visual novel than RPG. I'd rate it an 8 at most, but more likely a 7.5 because Dragon Quest XI S was more coherent and therefore a bit better. Both P5R and DQ XI S suffer from the same problem that they overstay their welcome and the game just goes on when you wanted it to end already. It's also a problem of Tales of Vesperia where the developers decided to add one more story arc instead of leaving it be at the closure of the main story that the game is all about. All these games are long enough already, so it's not a pleasant surprise to get another ~20 hours tacked on.
Persona 5 should have had different pacing where dungeons contain multiple parts and can possibly only be played on weekends. That way the time limits of one month would have had some back and forth between RPG gameplay and dialogues instead of the awful "play the dungeon for ~3 hours, then do ~7 hours of talking until the next main objective unlocks." There's also too much talk that keeps wasting time, namely the vast majority of messages you get on your phone in the game.
