It SHOULD. What's the longest we've had with games extending a world's story? You have Phantasia/Symphonia, Destiny/Destiny 2, Xillia/Xillia 2, Zestiria/Berseria... (am I leaving anything out?).
They should keep it simple, limiting to two installments in a "shared world" then move on.
The ToP/ToS world actually had five games lol: Symphonia, DotNW, Phantasia, Narikiri Dungeon X, and Summoner;s Lineage.
