Something important to keep in mind with this mod: You are a pirate, you're not here to stop the injustice, at least at first, you're here to beat people up and take their stuff, hopefully without dying. You have no moral obligation to follow through on, all that matters is your crew and your pocketbook.
How antihero your crew actually is will be mostly in whatever roleplay you put in, with a few exceptions of actions you can choose to do that are more/less heroic, but really the Lunatics are NOT heroes.
Another one is that you're the new gang on the block, everyone else is established. So you need to be careful not to take on more than you can afford to, your enemies want to kill or experiment on you, your allies don't actually like you much and probably wouldn't object to a firing squad. You're mostly free to do whatever, but you need to keep your usefulness to your allies higher then their irritation in having to deal with pirates or they'll break the deal.
Being lucky helps too, though.
To answer a question I remember seeing, it's not hard to get access to recruits, peasants are very easy to talk into adventure, and random Uber gangers aren't much harder. All it takes is research into the right directions.
