Few Japanese swordsman are as legendary as Miyamoto Musashi, and this series stars his son. The RPG is a lot like Dragon Quest, but sadly never saw a North American release. I'd love to see it finally available in English in an official capacity (there is a great fan patch, though)
One of the most legendary games ever made, Chrono Trigger is an icon of the role-playing genre. The SNES classic features an incredible battle system, and one of the best stories. Since the core has aged so well, a remake could really be something special.
Dragon Quest Monsters was essentially Enix's answer to Pokémon. While it never reached those same heights of popularity, it did fine in its own right and added some new spins on the monster capturing motif. A remake of the PS1 collection (which included the first two games in the series), could be a real success on PS4 since there aren't many games like it being made.
This wasn't a difficult choice to include. Final Fantasy VI is arguably the best role-playing game ever made, and it'd be incredible to get to play the SNES classic with a brand new veneer.
Square Enix aren't exactly known for their real-time strategy games, but Hanjuku Hero was the company's attempt at the genre in the late 80s. Unlike most RTS games, Hanjuku Hero is filled with humor, and I feel like its goofball brand of comedy could really succeed in today's market.
Parasite Eve has the unique distinction of being Square's first M-rated game, and the survival horror title was a major hit that featured a haunting soundtrack by Yoko Shimomura. A remake could make the visuals finally match the music, and on top of being a great horror game, it'd also be a blast of nostalgia.
The SaGa series' console debut was on the Super Famicom, and the 1992 stayed exclusive to Japan until it received an enhanced PS2 port in 2005. Now would be a perfect time to give the series a rebirth in North America, and hopefully it'd catch on as much as it has in Japan.
Let's face it. The most recent Star Ocean games have been a bit rough, to put it nicely. A remake of the 1996 original could breathe some new life into the series, and remind people why they fell in love with the RPG in the first place.
Released in 1993 by Enix, The 7th Saga had players attempting to find seven magical runes. While that seems doable in theory, the turn-based RPG also featured a notoriously high difficulty due to some odd localization changes. It never got a fair shot in North America due to this, and a remake could finally fix one of the company's past failures.
Xenogears is one of the greatest RPGs to never get a direct sequel (although Xenosaga served as a spiritual successor). The PlayStation title has a martial-arts focus, and features a fantastic story with plenty of memorable characters. It truly deserves another day in the spotlight.
