The Last Remnant
Let's start this off by saying that everyone's personal run throughs of JRPGs are going to vary greatly. What might have taken you 100 hours, might have only taken someone else 60. That said, we used a combination of our own personal experiences, matched up with HowLongToBeat data which allows people to submit their own times for a collective average.Kicking off the list then is The Last Remnant, a game that up until very recently, was one of the few exclusive JRPGs in the Xbox ecosystem. However, it is being remastered for the PlayStation 4 later this year. Assuming you're not blazing through the story, it's probably going to take you about 70-80 hours at least to complete this JRPG.
