We all know Ship Simulator is a simulation for sailing, not sinking. Although the whole purpose is to sail ships, ships sink in real life. Now maybe for realism, there could be missions where you'll have to save the crew from a sinking ship, by taking a vessel like the Arrie Visser out to the ship in distress, actually get on the other ship and make sure all crew members are safely on board your vessel, and then have to sail away before the larger vessel sinks, causing damage to the rescue vessel.
I used to be one for sinking when that feature came out, but now I sail and if I sink, I sink and just move on. I don't go around ramming other vessels or rocks just for fun. I'll admit I do so once in a while to see how I can handle being on a ship and see what would be a good possibilty if it was real. But one problem with that training is the ships sink in about one and a half minutes. Maybe a feature to control sinkings like bulkhead doors could help, and being able to launch the lifeboats(I think we'll be able to though)
But all in all, for my opinon, more realism in sinkings could be a good addition. I'm not saying that's all I want though. I'd like to see my ship where it should be, on the top of the water. Not miles below. Sinking happens in real life and in Ship Simulator, but let's all remember, Vstep designed this game for players to train for sailing and have fun seeing all the sights.
