Man, Atlus changed a lot of things in from Persona 5 to Royal and it's all for the better imo. I'll give several examples.
The "YOU NEED TO GO TO SLEEP" thing has been toned down a good amount. You're still stuck in Leblanc for the night after going to a palace or mementos, but you can do some activities (clean the cafe, read, study, make tools, etc). Makes increasing social stats easier.
Ammo for secondary weapons is refilled after every battle, which is great because I didn't like running out of that in the original game. Baton Pass is available for every party member without needing to raise their confidant ranks. Not only that, but after the 2nd palace, you'll be able to increase the rank of each character's baton pass. There's also the addition of Will Seeds. There are 3 in each palace and each time you find one, some SP and HP is restored.
So far, I've finished Madarame's palace and will be meeting Akechi when I resume playing Royal. :D
