Bloody...

After the excesses of Empire, Shogun 2 is taking a Zen approach. Though the word "accessible" is often code for "plain," in the case of Shogun 2, it's clear that the designers want to maintain a tighter focus on the core elements and not give in to feature creep. The unit roster is a great example of this. Rather than massive roster of units found in Empire, Shogun sticks with just 30-40 basic units (20 or so per faction), each of which has a clear and obvious purpose. This should give the player a chance to focus more on tactics than on the slight variations between similar unit types. If you need to keep an enemy at bay, for instance, you'll know to call on your Ashigaru spearman. To help add a bit of variety, units will upgrade over time.

Does anyone even remember the complete lack of unit variations in Empire?

One particularly novel development is the introduction of hero units. These are warriors who have perfected a fighting art and can carve their way through enemy armies without much trouble at all. Based on mythologized historical figures like the warrior monk Benkei, hero units are a nearly unstoppable force on the battlefield, capable of holding bridge crossings against entire armies, or smashing through a battle line to engage the enemy general. You can counter heroes with the right tactics, such as filling them full of arrows, or by having your own hero units engage them in duels. The development team may even consider letting players use political manipulation to sway heroes away from each other.

...what?!
