Hi Luc.
Yes, I think I would do that.
I have just worked on my first ever mission. I took DJM's first-ever mission and with his agreement, added AI, trigger points, fog bank around Alcatraz and so on), and I think it was quite good - "San Francisco Emergencies2" - needs add-on pack. I am now working on "Hovercraft in San Francisco", partly because DJM said he likes the hovercraft but mainly because I love the hovercraft.
I have produced many "missions" for MS Train Sim, and the Ship Sim is similar in concept. So the learning curve won't be too steep, I hope. Also, I am an experienced skipper (South Coast of England, living in Selsey, at the eastern end of the Solent) so I hope that will bring some realism to my missions.
My pet hate is missions that have so much AI that it is impossible to move. The sea just isn't like that (except around here during Cowes week).
