Hi Peter,
some of your statements are not much understandable, from my point of view ...
"And if someone wants huge ships like Titanic, the answer is no".
Pride of Rotterdam, Vermaas, Laatitude, Orient Star, Ocean Prince, should be considered as "small" ships from your point of view ? In fact, apart from the PoR, those are much bigger (longer, wider, heavier) than the Titanic (The Titanic was a reference when talking about huge ships ... A century ago - less two months). At least the game offers a wide variety of ships, with different purposes, sizes, and manoeuvering capacities. I personally never had the sort of morbid enthusiam about the Titanic, I reckon, and I don't miss her at all in the game. You would like to see her in the game, that's a personnal wish that I can understand, but you can't say that there are no huge ships in the game.
About the gun things, I think it has been told lots of time before ... This simulations is mainly focused on ships manoeuvering, and guns have no use in that. I'm personally very happy with that, there are quit enough games where you can use guns and any war and death things you can imagine.
Search lights could indeed be an interesting idea for some people. It's a little detail, but why not - at least it stays in the civilian focus of the game. In fact, there are tons of little details that could be added too. "Go and see", like you wrote with condescension. Eh, for example, aboard any ship, the cooking chief uses a potato-peeler... And that tool is probably used more often aboard a ship than a search light
