We should have the option to make ships, like pirate ships that can cross oceans without damage. We should have an upper and lower deck with chests and cannons and things. Just an idea. i Think it would be amazing to travel the world with a ship and actually live on it. Like an explorer.
To make it more realistic, maybe the ships should randomly spawn. Maybe have say, 3 classes of rarity. A small, medium, or large ship with villager NPC's or hostile mobs. Take the ship over by commandeering it possibly?
I would like to be able to make big ships and whatnot. However, like others have stated, this is vague. How would you make these ships? Would you craft different parts piece by piece? Would you place these pieces together in order to build a ship? This is what they mean by vague.
The idea is too vague. Like others have asked, how big are they? Is there anything in the chests on the pirate ship; and if so, what can be found in those chests? Besides that, the idea is pretty neat.
