I think Insomniac experience with the Latest Ratchet and Clank will be perfect as the foundation for how the levels work in this game.
Pretty much the same as TLOU but more explicit because each level is a different planet, where as in TLOU it’s a city or chapter.
but same premise applies, you have big open sand box to explore with out the need to worry about connecting each area and putting stuff in between each area. Or traveling to each mane area.
Each planet had its own distinct feel, density, creatures, etc and was big enough to explore and feel meaty with out feeling too big and laborious to travel.
