Anyway lets celebrate that for the first time in about 15 years we're going to get a mainline (offline) Final Fantasy with a well told story :')
XV had a good story on paper but it was butchered and told horribly. Lore was pretty much abandoned.
XIII story was told decently but wasn't very interesting, no key villians, plot twists or intrigue. Too much lore being left to datalogues.
