My day job involves creating emergency response simulations, so I was intrigued, coming back to London yesterday after (notionally) setting fire to an oil tanker ship, to see a new ship simulation game is about to appear on the market.
Ship Simulation 2006 seems to be based on technology developed for serious marine training by VStep in the Netherlands, and now acquired by Lighthouse Interactive, also in the Netherlands.
It seems to do for large ships what flight simulators have done for aircraft. You can choose your ship type, and geogaphical area, and various missions. Only a limited range so far – eg the harbours are limited to Rotterdam and Hamburg. But these are pretty interesting navigational problems, and Im sure it will develop more over time.
Theres an interview about Lighthouse here.
