Persona 5 is definitively the "big" JPRG of the year. I would recommend getting it for the story, the premise, and for the unique gameplay of the persona games. If you played Persona 4 or earlier you know what to expect, and this alone should be reason enough to go for Persona 5 already four months ago. If you haven't played one of the earlier games, know that this game is perfectly standalone, and will have qualities that people outside the JRPG fan base can and will enjoy. Even Zero Punctuation liked it, despite strongly hating on JRPGs in general. While I will not call it the best game of all times, it is still a solid game whose fundamentally awesome qualities and polish will make it remembered in 10 years. The only thing it lacks to reach the legendary rank is that memetic quality. And it's
really close to having that.
Trails of Cold Steel is by far the most pleasant surprise in the JRPG front this year. The game offers the amazing world building the Trails games are known for, and adds a ridiculously strong cast to convey a good story on top of it. The game is also fun to play, in short 3 out of 3 important pieces for making an awesome game are there. I must also add that it has drawn inspirations from the persona games, as there are relationship links in this game too. You might find the anime antics of the game to be a bit too much, or just about perfect - it depends on your preference really. Either way, the game is absolutely worth checking out if you have nothing more than a mere interest in JRPG games. If you do not enjoy the standard list of anime clichés, this game may not be for you though. I'm pretty sure Zero Punctuation would hate it
TLDR:
Persona 5 is a must buy for anyone not an outright hater of turn based combat games.
Trails of Cold Steel is a must buy for anyone with some interests in JRPGs. It's a really good specimen in the genre.
