The game is simple, survive in the underground seas, make a fortune, retire. Your enemies are everything around you, even your own mind. Terror builds while in the darkness, while in the light of towns and bouys (spelling?) your terror stops. Battlke sea creatures and pirates, ferry the dead, even deal in souls. All of this can be done on the Sunless Seas!
Music - Well done and easily matches the tone of the game. Fell in love with it right away.
Content - Thought not a high amount of ports things changes from time to time, so going back to a place youve been to may wield unexpected results.
Twisted Atmosphere - If it was only pirates Id have passed it up. Deep ones and dark creatures make this story a very interesting one.
Death - When you die, its game over like in any rogue like game, there is perma death though this is turned off in the merciful mode allowing you to save. However you can pass one of your Map, officers or skills to the next generation. I always recommend the map as its very useful.
Text Based Game - Not for everyone, I didnt mind it as enjoy reading and usually read lore and such in MMO's but it is not for everyone.
Money - Making money in this game is a slow paced process, though easy, it can be long.
