Persona 4 improves upon everything that Persona 3 introduced , the combat itself was fixed, as all party members can now be directly controlled by the player, and dungeons that while still tedious and sometimes boring are a marked improvement over tartarus.

The social sim aspects of the game have also been revamped with with the 3 social stats having been removed and replaced by 5 different stats, too account for the increased number of stats the game is far more lenient with free time than it's predecessor.

the gameplay is atrocious tartarus fucking sucks and the already mediocre story is ruined by shitty pacing

the combat is amazing though the quality of the dungeons varies wildly, the story however is the worst in the entire megami tensei franchise so far

it's like Innocent Sin but worse, It's still pretty good though.
Also making Maya into a silent protagonist is a crime

best story in the persona series so far, but also has the second worst combat

whoever designed the dungeons in this game needs too be shot

Story is worse than the original but it's still fun
