I hope it goes well, as Wild Arms is one of the best RPGs of all time, but the term, "Spiritual Successor" is something of a red flag for me.

It usually means similar visuals and gameplay, but a lot of the time there's so much that's different that it doesn't really feel like it's succeeding at anything other than being a knock-off.

Other times it just means they do a lot of cameos.
