Game that requires thinking.


Great strategy game! The only downside is the speed of the battles, that is definitely too fast. And the rest is brilliant. Music, politics, diplomacy, and definitely the best AI I've seen on the campaign map in the game. All alliances, coalitions and all diplomatic choices are of great importance.If you attack someone who is allied with other, his allies will come to his aid so reckless clicking is not recommended. Solid title.

Take TW Shogun 2 and multiply it by 100!!


NA: SOI has close to 2000 historical officers with each having individual stats and tactics. This is a game that is a lot more tactical, utilizes different diplomacy features, and has so much more depth to it than TW S2. It has every historical clan in the game unlike TW S2. TW is more about managing individual battles and has some diplomacy. NA: SOI is more about managing your territory with roads, farms, crafts, population, clan, officers, and building an empire to unite Japan. Both games are about historical Japan that is about it. In reality they are totally different. It's like comparing Mario Cart to an in depth racing simulation like iRacing.

A toned down total war game


Using real historical events this game requires a lot of strategy and real time combat in order to destroy your enemies and take over feudal japan. This all sounds great but it lacks a lot of depth that you just want to see after being able to do things in games that are half the price or even more at times. the performance isn't very good either, i had issues getting the game to start because it doesn't like fraps for some reason and then it crashed a number of times. Its quite a let down considering i had heard a lot of praise about this franchise.

An enjoyable strategy game in a long lasting series


Nobunaga's Ambition is a strategy series series that has existed for over 30 years, originally releasing in 2013, Sphere of Influence is the 14th title in the series. The series has some things in common with the Romance of the Three Kingdom series, even included some of the features that were unique to that in the early Ambition titles. The game has ten different scenarios as well as a tutorial, with more available as DLC. You are also able to create your own custom characters that you can play as, this system allows you to choose your face, personality, stats, lifespan, and parents. You can also view a directory of historic officers and you can edit their stats. When you go to start a game you are given a variety of ways to edit the games difficulty and options for using or not using created or edited officers, if characters die as time goes by, if characters can die in battle, if you can turn maidens into officers, if character's common or true names are used, etc. After you choose a scenario you will choose what clan you want to play as, this will give you an opening event for your clan and each clan can be given quests and goals to complete based on their historic actions, completing these will aid you. Your strategic options will be familiar to a lot of people who have played games with a similar style, every turn is one month of in game time, you will be able to take actions such as covert spying on other areas, attempting to hire other officers, attempt to get another clan's officers to join you, build to improve the areas that you own, create groups to go to war, increasing small tribes support of you for further bonuses, diplomatic options, transferring your officers to other provinces, explore your territory, etc. Each province will have a crops, crafts, and conscripts number that you can increase, crops will lead to a higher population growth, crafts will increase your income, and conscripts will be used to build your armies. These stats can effect each other, you might not be able to increase your conscripts if your population is low due to your crops rating. Building and increasing these three things each month will use up the total labor that your clan possesses. In order to accomplish other actions, such as raising relations between you and other clans and tribes, you will need to send your officers out to complete the job. Managing provinces can become annoying and tedious, especially late game, but you are able to set them up to automatically take care of things for you. In each town you are able to construct things such as stronger walls, tower defenses, gates, villages, temples and other things that will increase either the defense of your city or give you different positive and negative effects. Battles take place in real time with you setting targets for your forces while your officers can make use of different traits and abilities. Officers may learn new traits or improve their abilities through battles. Sphere of Influence is really good and gives enough difficulty and complexity to be more difficult than simple strategy games but not as difficult as something you would expect from Paradox, the game also gives a lot of historic information making it interesting for people that want to learn about the time period.
