I kinda have to agree, there are many other items that could be added as dlc, some have already been mentioned many times:
Like:
- Ship flags (dlc that enables you to choose between alternate flags for your ship, usable x numbers of times)
- Ship name (dlc that allow you to name up to 10 ships for example)
- Ship paints (dlc that allow you to paint 10 paints for example)
- Bait (dlc that gives you +20% chance catching fish/bottles etc for 2 hours, usable 10 times)
- Smuggler (dlc that allows you to enter a stealthy mode enabling you to enter enemy ports even if you are not in a trade ship, (last for 2 hours, usable 5 times)
List goes on just a little imagination...
Things like this that once all used you need to buy again... will not really affect gameplay in terms of "Pay to Win", and also will generate some funding.
This ship dlc only 1 time funding for the game, sometimes need to to think abit longer term.
