I've seen both these ships at the shipyard in New York, but I have yet to see anyone using them. What is the purpose of these two ships and are they worth buying? I suppose the prisoner ship could be used to transport prisoner pods from -where ever- to prisons, but you can do that with any ship. As far as the Luxury Liner goes I see no practical use for this vessel, other then what it says in the description "A party boat", and I can't remember the first time I had an opportunityto have join on…
