From what I've seen, it seems to be a slightly more mature JRPG. The combat seems to be typical. There seems to be a ton of battles and not much story.
I only picked this up in the first place because Hideaki Sorachi said he liked it.
If I had to make up a review off the top of my head, probably 3/5
I've only played like 30 minutes and skimmed through some playthroughs so take everything with a grain of salt.
