I already left a comment before, but after watching the latest developer video again featuring the surfing mini-game and free diving, another idea came to mind.
I really hope these activities won’t just be mini-games that you play two or three times before moving on. It would be much more engaging if they had meaningful goals, such as time trials, medals, NPC opponents to compete against, or even leaderboards.
For example, if a Zoi chooses to become a surfer, their performances could improve their surfing skill, earn them money, unlock new equipment, or qualify them for more prestigious competitions. That way, these activities would have a real impact on the Zoi’s life and progression.
The same applies to scuba diving. If treasure hunting is added, I hope treasure locations are randomized for each new save. Otherwise, once players know where everything is, exploration quickly loses its sense of discovery.
I’d also love to see spearfishing, with the ability to sell the fish you catch at your own market stand.
Overall, I think it would be great if every activity was designed with replayability in mind. Meaningful challenges, progression, rewards, randomness, and interconnected gameplay systems would encourage players to keep coming back instead of having the exact same experience every time.
But underwater hunting and different treasure locations — yes, I’m on board with that. The main thing is just that they don’t spawn randomly where they might be inaccessible for harvesting — there’s always that risk. However, if we go the same route as with sand piles, which appear in set locations but you never know if they’ll be empty or if you’ll find something (in the underwater version — chests or distinctive seaweed bushes on the bottom) — then yes, that could work
