Windward Horizon on Steam

Trade, quest, fight, or simply set sail and enjoy the ambiance in this charming open world naval RPG. Sequel to Tasharen's fan favorite game Windward released on Steam in 2015.

I remember playing the original Windward and it was fun though it stopped getting updates before it could get really good. I tried the demo of this new sequel and it looks like it could be pretty fun.
