Aproximated length of the finished game (story campaign)

[RomoloHero]

Something I noticed. At the town square there is a map of Isola Sacra.

The map:

This is what I think they are, I am fairly certain about 1-4 but 5 is partially speculation.

1. Mariner’s Keep (Door here that probably leads to area 6)
2. Orban Glades + The Shallows
3. Sacrament + Sewers (Gate that leads to 4. Nameless Pass and Gate that leads to 5. Marin Woods)
4. Nameless Pass.
5. Marin Woods (100% Sure) + Lowland Meadows & Hunter’s Vale (probably/maybe idk)
6. ???
7. ???
8. ???
9. ???
10. ???
11. ???
12. ???

I do hope we are at most at 25% of the story.
