Almost an awesome game!
This is almost an awesome game. I just have some suggestions.
When you capture a town, you should get compensated with men, weapons, and money. People do not raid towns without taking anything, realistically. There is just no incentive for capturing towns. Also, when you capture a town, that town should be "yours" in the since that you get a discount on anything you want to buy. Think about it. If some pirate came into your town and kicked your ass, you would probably give him a discount so he doesnt do it again.
Don't listen to these jaggoffs about poor graphics either. I like this type of graphics. Fucking idiots dont know that they are supposed to look like that.
Also, creating more upgrades than just cannons would make this game so much better. Upgradeable games are my favorite. If you took my advice on all this, I would play this game all day, no joke.
