D. Ballard - Titanic: Challenge of Discovery
Publisher: Panasonic Interactive Media, ISBN 1-892461-04-8
This is a good simulation game. You work your way from the Iris and Bismark, which give you the necessary skills to dive and find the Titanic. You get to see that it is no walk in the park, unless it's Central Park in the middle of the night, 13,000 feet below the surface. I recommend the game, it was $27.99 at Best Buy.
