I have a wishlist o in-game things I want to have in the future. Airship or hot air balloon Different types of large mast with sail. If a submarine is too sophisticated, how about a diving bell.Attached it to your ship, it can also resupply your oxygen underwater. Catfish only live in freshwater in real life, a freshwater fauna is needed. New weapon: blowpipe, it could shoot paralyzing dart and poisonous dart.Some kind of fish could be used as material. Friendly villagers and village, you could even hire one or two.And merchant ship with vendors, you can trade with them or rob them(their ship will fire back if you attack them) Gun/rifle with bayonet. Mystery island is not that bad, but it seems that they need to have less bug.Besides, some side quest could be added as a complement. Instruments, some could be carried by player. Exploration should be the core of exploration mode, maybe we should have some kind of exploration diary, which contains every kind of animal, plant, resources, npc and so.
