As someone who hates Soulslikes but loves FF, I thought it was great. Loved the worlds themed for the different games, plus the story was fun and walked a nice line between serious and silly.
I do wish that the DLCs weren't gated behind the high difficulty levels, though. I would have loved to continue on into those fights with WoL and the Emperor and such, but there's no way in hell I'm subjecting myself to the level of Soulslike masochism that it would actually take to do it.
