She is intended to be added later on. Just be patient.
I love the Titanic, and it is the reason I started using shipsim, but then I got to using the other vessels, and I really started getting into it. I have really high specs on my pc too, so the graphics look awesome. Can't wait for the mission editor and Titanic so that I can have several boats sailing around her in the harbor.
This also raises a question, will sse have the unlockable free roam camera as did ss08?
