Advanced Cooking, okay that sounds, complex?
But let me explain:
Cooking isnt an really "Hard thing", basically everyone can Cook something, that is fine, but for an Roleplay Point of View Its nice when someone is like the ship's cook, the person who is really good in cooking and stuff, let me explain a little bit further:
The Cooking mechanic is REALLY basic, its just pressing 1 Button basically, but what if you can have spices? You could cook the meal and spice things up?
On every Island are Plants, but what if some of these Plants can be collected and used for spice up the Meat that is burning on the stove? you would need to perfectly balance the amount of spices, if you do to many the Meat isnt healing that much, but if the Meat is spiced perfectly it heals more, also how about a Trading Faction that wants to have rare spices?
Just some random thoughts ;)
Also you could cook new stuff, like Fish Soup, if you mix various Fish species together you will get different soup, and every Soup has an different level of Healing or other Effects. So you can really like do a "Cookbook".
What would you guys say?
