Modernization of Japan - but where are the Western powers?

This addon to the main game Shogun 2 plays 200 years after the events of the main game and heralds the modernization of Japan.
There is a power struggle between the Shogun- and the Imperialists clans. The player can choose sides and change in the current game or the sides. The mentioned Western powers to bring out the modern technologies and limited European units and veterans agents not really much with it. Since this should be a big factor and the cover also manufactures indicating, but not really delivers what it promises, this costs 2 stars .. I had the Western powers expected as playable nations, who actively participate in the fight and build their colonies , A pity.
