Ganryu isn't the greatest game ever made, but it's exactly the kind of game that I enjoy and it's a dang good one if you ask me. It's a quick romp through feudal Japan that uses an interesting conceptual hook, features lovely visuals that thrive off of inspired choices instead of what's conventionally impressive, offers action that's both challenging and strategic while maintaining an excellent balance the whole way through, and it takes ideas from other games that I happen to really like and uses them effectively. I think it's one that's quite underrated and absolutely worth your time if you enjoy any of its inspirations.
Star Ocean: Integrity and Faithlessness
SO5 was quickly dismissed as a mediocre game and a disappointment compared to past entries, but I couldn't disagree more and firmly believe that this game is long overdue for a re-evaluation. This game captures everything that makes the series special even within its smaller scope and budget and is absolutely worthy of standing with the rest of the series as one of its strongest entries. Combat is an absolute delight, the story offers relevant themes and tells its tale in a way that's unprecedented for the genre, it features some of the best characters in the series, and it offers all of the tinkering and depth that I associate with the series. If you come to the genre only wanting best in class visuals, lengthy cutscenes, or turn based combat, this game isn't going to do it for you, but for those who want to see what JRPGs can do when forced to innovate within extremely high stakes and with limited resources, SO5 is perhaps one of the most impressive cases of "greater than the sum of its parts" that I can think of.
