Okay. My picks would be
Lightning Returns: Final Fantasy XIII
First game in the trilogy to have actual quests (lots of fetch stuff, but some are pretty interesting and even have split paths) and a pretty open world. Not huge, but interconnected, changing with the time of day, and can be basically be tackled in any order. It's a far cry from the linearity of FFXIII. Battle system is cool, and a natural extension of the Paradigm Shift system, which was probably the most intuitive part of the first two XIII games. Music is awesome, as usual. And there's a lot of pretty cool references to past games. That, and a couple of unique ideas (like the ability to make monsters go extinct) and a time mechanic ripped basically wholesale from Majora's Mask, and it's a pretty rough gem.
Kingdom Hearts: Re: Chain of Memories/Kingdom Hearts: Chain of Memories
Basically the closest KH has ever come to being a "classic," turn based RPG. The battle system is card based, with cards power relating to the number printed on the face, from 0-9. Playing a higher number than your opponent breaks their card, which can stun or otherwise disadvantage them. The player can put up to 3 cards in one action creating a Sleight (three Fire cards make one Firaga, etc) and by end game you can pull off some pretty cool moves, including Final Fantasy staples like Mega Flare and Zantetsuken. The game even includes a second campaign with Riku, who plays pretty distinctly from Sora, kind of a Dante/Vergil deal. The story, including the Disney elements all tie around the theme of memory and how it's related to identity, and if you get past the Nomura weirdness (or just play it as a standalone) it's pretty mature for the standard KH fare. Most streamers skip it during their KH playthroughs opting to watch the cutscenes instead, and I feel that's the crowning achievement of the game, because it's mostly GAME, saving the word salad storyline for segments before and after levels.
