I've been slowly working my way through Persona 5, and it makes me realize just how long it's been since I've dug my way through a good JRPG. Part of it is because the medieval fantasy JRPG formula went stale on me a long time ago, but also because they haven't evolved much from their roots; talk to people in a new town, buy new equipment, go into the new dungeon, and repeat as you take a tour of the world.
A good plot certainly helps too.
The Persona series has always been different for taking place in a contemporary setting and that you don't jet around the world. Aside from a field trip, you probably won't even leave town. The third game in particular laid the groundwork for successive installments. It implemented the current system of balancing dungeon delving with having a successful life as a high schooler.
Having the systems feed into one another was a stroke of genius. Bonuses earned for the social aspects of the protagonist's life, apply to the creation of more powerful personas for combat, and money earned from dungeon delving in turn funds the protagonist's social activities.
It introduced a unique playstyle, and rather than visiting new towns, there's just one main town that actually looks like a town with different neighborhoods and districts. As the calendar year passes, dialogue changes, the store offerings change, making for one really good, living location instead of many lesser ones.
And because of its contemporary setting, the Persona games aren't about fighting nations or overthrowing some empire. The end bosses are typically some supernatural entity that most of the world is completely oblivious to.
Persona 5 adds something new though, that I find particularly invigorating.
It makes everyone a thief.
Usually in JRPGs, the thief is a weird class. Their combat skills are mediocre, their rate of stealing items is poor, and it's hard to find any justification for putting them in a party other than because the player likes thieves or wants to steal a specific high level item. (Occasionally they might class promote into a ninja or something that makes them useful, but vanilla thieves tend to suck.)
Specially, Persona 5 makes the entire party a group of phantom thieves and then completely runs with it. All the cool stuff you expect a gentleman thief to do, like leaving calling cards, and doing bold and daring heists, are things that the protagonists accomplish while the player is at the controls. And you can see that the development team had a lot of fun with it. You know how in movies like Ocean's Eleven every member of the team has a job? There's one heist where the party does that, where they split up and everyone's got their own thing to do at the same time.
In most JRPGs, if there are visible enemies, it's a case of you see them, they see you, and one of the two parties charges forward and attacks (maybe even both). But in Persona 5, you're thieves, so you can hide behind objects and ambush your enemies. This is crazy fun and feels like it rewards players who actually act out the part of a thief since ambushing gives everyone a chance to attack before their enemies in the first round.
The dungeons are built specifically to have gimmicks for the player to maneuver around, whether it's something to hide behind, infrared sensors to slide underneath, or air vents to crawl through. And though I'm calling them gimmicks, they don't feel cheap at all, because they're there to sell the fantasy of being elite phantom thieves and they do!
Rather than simply have treasure chests all over the place (though there are quite a few), the player also has the ability to loot certain items that are part of the scenery, so grabbing vases and sculptures is desirable, since the player can sell those items later.
When you exploit the weaknesses of all enemies present in a battle, you enter a Hold Up, which features all members of the party surrounding their enemies with their guns out, and you can actually demand for money or items in order to let them go.
There are so many nice touches, from the costuming, to the code names, and even the annoying nights I had my protagonist working on making lockpicks so I'd have them ready to go the next night we went into a dungeon.
I can't remember the last JRPG I played that's worked so hard at selling a particular fantasy, and probably the thing I like the most about it, is that there are plot reasons behind a lot of what they do. The characters don't have crazy costumes just because they happen to like cosplay, just like they aren't sending calling cards just because they want attention. When the plot and the game design support each other, it really makes something fun.
I'm at the end of July (in game) now, so I'm still less than halfway through, but I'm looking forward to the rest.
