This looks really interesting, but what's the objective, I'm curious? :P
So it's going to be an exploration/inventory management/trade game where you control a trade ship and you have to sail across a big, unmapped ocean to both find and trade with multiple islands with a procedural economy. You can set a course and sail in any direction indefinitely while you manage your inventory and stats and stuff so sailing isn't too much of a bore, but you have to pay attention to where you're going because if you crash while you're moving too fast, the game's over.
The main goal is pretty much to survive and to make as much money as you can at the moment. I guess I should come up with an idea for a win state, though, huh? Haha!
Sounds cool! As for a win state, could always have a few options, some potentially endless games have life goals, such as amassing a certain amount of money. You could do that, and add it other more fitting elements like' Find X number of ports, Sail X distance, etc. Then the player could choose whether it's going to be a short game or a long game. :)
