This is the kind of game that will last forever, will keep playing this game. It's difficult to learn the game initially, but you will quickly learn it as you play the game. Oda clan under Nobunaga is a good beginner clan to get into the game, hell it's his game.

A truly good game, fully recommend to start with the franchise, be wary that actually only 2 DLC are truly worth it (look on the reviwes of the DLC to check for it) although if you can get the Japanese version of Ascencion that one is probably better since 1- Ascencion comes with all DLC (the english release also has this one) 2- in ascecion you can actually marry your created female officers, in base Sphere of influence all your created officers are actually male even if it says female trough a workaround with the event editor (non existing on SOI, but present on the english and japanese version of ascencion) 3- because the japanese/chinise modding community was able to create the tools to kinda fix the enourmous AI issues, sadly the english and japanese versions (read well is version, changing language of the game wont help) of the game use code different enough as for the tools to not be functional, maybe some day someone will be able to create english version tools

Nov. 2025

This game is great if you love grand strategy. I've been learning so much about the Sengoku period from this as a lover of Shogun 2 and the Samurai Warriors series

Sept. 2025

The BEST Nobunaga's Ambition game, before Koei Tecmo ruined the franchise by recycling this game over and over again. If you're unsure which Nobunaga's Ambition to play, pick Sphere of Influence.
