I had the game on medium and ended up with 45 ships I had 2/3 on charters went very well until I overwrote the game save file
I have restarted the game this time in Hard mode to see how it plays out and even in hard mode its playable you do have to put some thought into it though
There is word it may become multiplayer as well
What I have learnt is that ships degrade in Eco rating as they get older and after 25 years they may sink if they don't sink before hand due to negligence.
Some screenshots of the hard mode and medium mode note you can purchase ships with a bank load this was a VLCC i purchased and you can paint it as you wish with the colour pallet provided.
