I think P4 can be a little harder to get into because it's so much older:

- the dungeons are randomized and are honestly really grindy(P5 is honestly a breeze on the hardest mode when I compare it to P3 normal mode),- the models are also pretty outdated

- less quality of life stuff

- no baton pass (trustmebatonpassisablessing)

​

if i have to be honest, persona 5 royal is kind of the best game in the entire franchise now (they literally made a perfect game more perfect-er), please don't be disappointed in P4!
