I only have the demo Ryan, but by the looks of things I think it is adding the money to your account.
See...
That was after 4 sailings.
EDIT: I thought you might like to know though coyote, I have played both demos.
Ports of call: deluxe 2008 & Ports of call: XXL .
And in my honest opinion, the Deluxe 2008 may seem better as it was intended for commercial retail but!!
It is only available to manage a container ship copmany!!
Where as the XXL game is available to manage a company what ever you want it to be!
Cruise ships, ferries etc.
And it is soooo much more detailed, like choosing the cargo fuel consumption etc.
Even the guy who makes them admitted he preferred that version!
If you do buy the XXL one you also get to play 3D as well!
And you can add infinite ships like well known cruise ships and ferries and over 200 more 3D ports! :O
Look at all the add on ships!
