The Persona 6 reveal could hardly have been less informative, so we've no choice but to scrounge the newly minted store page for something of substance. At a glance: not a lot, but not nothing.
For my money, the main takeaway for the Persona 6 store page is what Atlus isn't doing – namely, fixing what isn't broken. Compared to previous releases, the studio is also strongly emphasizing approachability – presumably hoping to bring all the people who bought Persona 5 back for another game.
