If boats make it too easy, add sea/river monsters. NOWHERE IS SAFE. NOT EVEN THE SEAS. OR THE RIVERS.
I’m mmmmmk with boats, I’d love to see some sort of water vehicle. My only problem is that I feel it’d be kind of useless except for crossing rivers without drowning in the games current state. If we get more water features (oceans, lakes, a water dungeon? o.O) they’d be much more useful.
