I bought the early access of Sunless Sea edition from Steam and have put around 40 hours into it. I have also been following the updates closely, and I’m really looking forward to what is to come in the future. I would like to put forward two suggestions for the light aspect of the game, with the idea to spend money to prevent terror before it occurs, rather than trying to lower it afterwards.
Sell flares at the Wolfstack Docks. Flares would be a sailing mechanic (as well as a combat mechanic), which would be triggered by the F key (bind Full Power to P - this will also prevent accidental engine overheats through mistypes), which then lights the sea around you for 4-5 seconds for a similar radius as one of the light buoys. The positive aspect of this would be to prevent terror during lightless stretches, thereby saving yourself a 2-3 point increase. The negative aspects would be the cost (say, 30 echos per flare), the loss of 1 hold space per flare, and maybe the increased possibility of attracting sea beasts or one of the more negative wandering phenomena referred to in the upcoming aquamarine update. Flares could also be used in combat (as fuel currently can be), though this may change significantly in the Steel update.
Invest in the Admiralty. Once you have Admiralty’s Favor above 15, you have the option to invest with them to increase the amount of light on the sea. Initial investments would start low (say 50 echoes), which would put an additional buoy in a random position near Fallen London. Increasing investments would place buoys further away, place double lights or increase the width or distance of lighthouse lights, and maybe providing fuel/supply sales at lighthouses. Results would be random and fairly unpredictable, but would allow for more travel with the boat light off and perhaps eventually bridge long gaps.
My two cents. Opinions, comments, suggestions welcome
