As a player I do consider the world when when I make my character. It is in fact very important. What makes it so important is that the DM works with us to help build the world around our characters. It is it his or her world, but our shared world. That is the flexibility that builds buy-in IMONice to know you can brush off someone wanting to have a living, logical and consistent setting with several variations on ‘does it matter?’ And ignoring the actual point that all those questions were leading up to, the player doesn’t consider the world when they make what they want they just make it.
A player just wanting to crowbar in an entire settlement to a constructed world to facilitate their character seems akin to someone taking a marker to someone else’s painting because ‘well I thought it would look better with a tree there’
