I've played until reaching Honolulu... which took me around 6 hours since I want to explore everything, collect all loot (even if it respawns) and participate in every minigame.
I'm liking it so far, including the new cast. I have to admit the graphics can be underwhelming and somehow I didn't have that problem when I played Infinite Wealth. The grassy surfaces can have flat low-quality textures, some character models lack details and the ship doesn't ride the waves in a realistic looking way. Plus I think that the framerate can drop a bit sometimes during storms (playing on PS5).
