NOBUNAGA'S AMBITION: Sphere of Influence reviews and comments

NOBUNAGA * S AMBITION: Sphere of Influence is, in my Opinion, a very good Strategy Game. There are good Tutorials and at least the Basic Is explained to each point, the Rest comes almost by "learning by doing" on its own. The Economy in the Provinces that one owns and also the Money system is very simple and especially well implemented for beginners in this Special Genre. What I find a bit Negative I find that there is no multiplayer/Multiplayer mode, just such a Mode would certainly help that even more People would buy this Game, because I know many who just for this one Reason did not buy the Game. Now I have to admit that Sphere of Influence IS my first NOBUNAGA AMBITION * S Game and therefore I do not know the Predecessors and cannot judge the game from the older Parts. However, I was Surprised from my Side Positively and Find above all the Historical Background, which is represented by many different Scenes in the Campaign Graphic, beautiful and well implemented. So If you want to look at a little variety of Multiplayer Games and gamble against yourself, I can Recommend NOBUNAGA * S AMBITION: Sphere of Influence.

Very interesting Strategy game. The Price may seem a bit too high at first, but you can spend a lot of entertaining Hours on it, so as always this is relative. For me personally, every Penny paid off. Pros:-geographically and historically correct Map of all Japan-countless Clans, all playable from the Beginning, with several different Scenarios (Starting point for Campaigns)-a lot of hiring opportunities for Campaign (Aggressiveness of AI, Crop yield, mit/without Quests and Events, etc.) -extensive Expansion of the Castles (Fortress and Surrounding Area) and the Road network-Bau/Foundation of new Castles in almost all parts of the Map (Place predetermined, but very many to Choose from)-very many Characters with different Abilities, which are free for certain Tasks (Lord, General, Supervisor, Construction, Diplomacy ...) can be used-extensive and good loyalty system and many Opportunities for The development of the Characters-interesting and well thought-out manageable Diplomatic System, even with Senvolen Alianzen/Coalitions Neutral:-quite simple Military system (only 3 Unit species), but also clearly transparent-Castles have different Limits for Expansion (Fortress and Surrounding area), but is an additional strategic Component-neutral Traders where you can buy Goods and sell grain, but no Trade between the Clans (for People who like to have more complex Trading Systems, this is probably rather negative) Negative:-no Possibility for Modding (E.g. to create your own Scenarios)-no German Localization (not a real Problem for me personally, but for some perhaps obstructive)-some Windows (E.g. overview List of all Clans, Castles or Characters) are very cumbersome to reach; Here some Hotkeys would be helpful The Game also offers so much that I personally but not or hardly use, such as an Editor for Characters or Quests and Events (I usually play Sandbox). Everything in all clearly outweigh the positive Points, hence a clear Buy recommendation.
