Its clear you are not a M&B player. Its supposed to be a sandbox, not a themepark and there is already a deep detailed Diplomacy mod adding a lot of content, just like before...and that is without detailed tools and knowledge of how things work. We do not need the developers for it.
A sandbox only requires a box and the sand. WE use the tools, to make the content. Just like the previous games. The originals and their expansions had LESS than this game already has. That, is reality. That is what made this series great...the MODDERS. Deal with it.
A sandbox game does not (and never did!) mean that it's supposed to be a playground for modders! Sandbox means a place for the player to do and become what he wants, with all the possibilities and depth to do so.
I don't know why this doesn't go into the heads of all you mod fanatics - we payed for a game, not for a development toolbox for some modders!
