Some folks are working on an independent video game (for PC only) entitled “Titanic: Honor and Glory.” In the game you can simply tour Titanic, or work through a story wherein, once the sinking begins, you have two and a half hours to make your way off of the ship and survive. It looks pretty darned cool.

That game looks like it is going to be really good. I just downloaded the free early demo, i will check it out tonight. I had a PC game in the late 90's called Titanic : Adventure out of time. It was really cool you got to explore the ship and try to get off it after the collision. i will have to try and find it on the web to play it again.
