NOBUNAGA'S AMBITION: Sphere of Influence - Ascension offers a deep and intricate strategy experience that appeals to fans of historical simulation and grand-scale empire management. Building upon the foundations of its predecessor, the game introduces a wealth of enhancements and new features that elevate the complexity and immersiveness of the gameplay. Visually, the game maintains a traditional aesthetic that faithfully captures the Edo period of Japan, with detailed maps, character models, and art styles that evoke the atmosphere of feudal Japan. The interface is user-friendly for a game of such depth, allowing players to navigate through various menus and strategic layers with relative ease, though the sheer volume of options can initially feel overwhelming for newcomers. The core gameplay revolves around political maneuvering, military conquest, resource management, and diplomatic relations. Players take on the role of a daimyo, aiming to unify Japan through a combination of warfare, alliances, and strategic planning. The game’s mechanics are robust, offering multiple paths to victory—be it through military dominance, economic strength, or diplomatic influence. One of the standout features is the detailed combat system, which emphasizes tactical positioning, troop types, and terrain advantages, requiring players to carefully plan their military campaigns. Additionally, the game introduces a dynamic event system that can significantly influence the political landscape, forcing players to adapt quickly to changing circumstances and rival strategies. Ascension’s new features include expanded diplomatic options, more complex court politics, and a refined management system for provinces and resources. Diplomacy is no longer just a matter of declaring war or forming alliances; it involves intricate negotiations, marriage alliances, espionage, and managing the loyalty of vassals and retainers. These elements add layers of depth, making each playthrough feel unique and unpredictable. The AI has been improved to provide more challenging and realistic opponents, capable of forming alliances or betraying players depending on the situation. The game’s economy system is also notably detailed, requiring players to balance taxation, trade, and development to sustain their armies and maintain stability across their territories. The strategic depth is complemented by a compelling narrative backdrop, immersing players in the turbulent era of Sengoku Japan. While the game does not feature a traditional story campaign, it offers a sandbox experience where players can craft their own historical narrative, whether they choose to emulate the legendary unifiers or forge their own path through conquest and diplomacy. The game’s soundtrack and sound effects further enhance the period feel, with traditional Japanese music and ambient sounds contributing to the overall atmosphere. The multiplayer mode allows for competitive or cooperative play, adding replayability and social engagement as players test their skills against others or collaborate to achieve common goals. Overall, NOBUNAGA'S AMBITION: Sphere of Influence - Ascension is a comprehensive and rewarding strategy game that captures the complexity and grandeur of feudal Japan. Its depth and detail make it ideally suited for dedicated strategy enthusiasts who enjoy meticulous planning and long-term empire building. Although its learning curve can be steep for newcomers, the game’s depth and the variety of strategic options ensure that each session offers fresh challenges and opportunities. With its refined mechanics, historical authenticity, and engaging gameplay, it stands as a strong entry in the series and a must-play for fans of historical grand strategy, offering countless hours of immersive gameplay that rewards patience, strategic thinking, and a keen understanding of the period’s political and military dynamics. Rating: 7/10

Still one of the best entries in the Nobunaga series. Ascension (this specific version of Sphere of Influence) captures the progression from mere Officer to Daimyo wonderfully. You start small with your own little hamlet where you build a small insulated economy through a basic yet rewarding (spatial) puzzle mini game. Then you progress to be a player on the actual campaign map - perhaps you are given a castle to rule, or at least to administer. From there, you start to rule multiple castles and provinces, become the daimyo of your own clan. The final stage is then to have a clan so powerful that you have leaders that rule entire provinces for you, and execute military campaigns without your micromanagement, but merely following your high level orders. Apart from this, the game of course features all the important characters from the sengoku jidai, and has a good amount of historical events. Definitely recommended for anyone interested in this time period of Japanese history, and for any fan of (character-focused) strategy games!

If you like RTK XIII's RPG elements, this game is similar. You get to do some city building early on, and carry it onto your main game. All about the "All Officer Play" mechanic from KOEI.

I made the mistake of listening to the reviews saying to get just the SOI version instead of this. Dont get me wrong i loved SOI, but i wanted to try this out because the thought of playing a subordinate appealed to me despite the warnings from others. So after trying it out i instantly got engrossed with running my own town and completing missions from the daimyo. I loved the change of pace of being just some underling moving up the ranks. I didn't see or got bothered by any of the so called negatives that others pointed out, and the little changes this game made from SOI is so tiny that you wont even notice it. Being an officer serving a daimyo adds such a great layer of gameplay, and you actually interact alot more with other officers in the clan, feeling like you all are working for the same goals. I went from just a lowly officer being put in charge of running my town being tasked with contributing to the clan effort, being promoted several times along the way to a regent, given command of several castles and fortresses with a mission to conduct entire wars against specific clans on behalf of the daimyo, i enjoyed this game alot more than i did SOI, if you like a bit of roleplaying aspect in a grand strategy game, i definitely recommend this, you will not regret it.
