Incomplete areas inside a game world does not mean there was content cut or held back. When I would work on game world I would create the entire map first all of the different areas and locations that would be part of the game. Through development and under strict time frames you may realise that some content might not be complete in time for set release schedule and thus you would block off areas of the game to allow developers to continue developing without worrying about players accessing said areas and discovering broken code and or no content. Its just how game development works. If a game can give a player 80+ hours of entertainment I would consider that fair. If you play it for 100's of hours and complain about lack of content, I think you need to reevaluate life.
