They intergraded ff12 and tactics lore into ff14 well without needing to play those games and made those worlds feel apart of ff14. The only series that told a crap story that wasn't intergraded well was the nier raids. There is also plenty of lore videos for ff11 without the need to buy and sub to the game that someone is currently doing for ff11 covering every expansions story and someone else has done lore for all the beast men and other various lore.
