An Essential Co-Op ExperienceHintzke | Aug. 12, 2013 | Review of Total War: Shogun 2
If you've played a Total War before there isn't much different in this game from previous entries into the series, with the obvious exception of settings and units. As is the campaign is solid and has all the things that make a Total War a solid game.
However, it's true shining moments are in the Co-Op campaigns. There is something about marching your armies against common foes and struggling in battle as thousands of units clash just to have your friend come from the fog of war and rally to help turn the tide. It doesn't happen a lot unless your partner plays pretty close, but it is definitely worth the money just to experience these moments.
The cons to the game is its optimization. I think they could have did a better job, and at times it's recommendations for your settings are pretty bad and will cause terrible frame rates, so it may take a bit before you get a solid un-bogged down battle.
All in all, it is a very solid entry and is a great place to start as well.
