Hi oliverh,
since the beginning of the "Ocean Star"-construction we are talking about that theme with the developers at VSTEP! Well, there are lots of new larger cruise lines with conventional propulsion system, that's why the "Ocean Star" got it too. But there will be of course more than one azipod driven vessel in the future of ShipSim, maybe a tug first and than ferries or cruise liners. For sure!
Cheers
