That's just my opinion but I think Easter eggs in Build mod are far too easy to find and kinda spoil the game's climate. I suggest hiding them better somehow so only hardcore players would be able to find them. The most eye-blazing are the guy at Nevis pirate house and some other names and dialogue references (Maltese monk's dialogue for example). The books are rather unharmful in my opinion. Maybe we could also make a secret location like the developers did in the maze? These are only my thoughts and I respect all Build mod creators of course.
