What is the point of Overworld in the game?

[Izar_Chillen]

No point really. Apparently it's too hard for Square to design interesting and living openworld

The crummy engine couldn't handle it anyways

They had to move the Dwarven Beast Tribe quest hub to Lakeside due to memory limitations as it couldn't handle having it in Kholusia where their home is and the map is hardly bathed is massive detail.

Actually, they did bathe it in massive detail for YoRHa. That's what caused them to hit the memory limits. Those areas you explore for the YoRHa quests are included in the Kholusia map memory. There's also the "hidden" detailed backdrop visible from the top of the skybox over Komra if you completed Puppet's Bunker (or at least I don't think it's visible until after you complete it - it's not visible to my alt that never got past unlocking Copied Factory).
