Ship Simulator 2006

"Ship Simulator 2006 doesn't have the feature-set to compete with sims like MSFS and MSTS, but it's a solid start. The developers are already talking about the next instalment and making encouraging noises about wave modelling, long voyages, and multiplayer (not included at present). Unless you've got salt in your blood, I'd recommend sitting on the dock of the bay until SS2007 arrives."
