The speed, accelerations and physics of the units are taken to realistic levels so not only the battles feel more realistic but now you must plan your tactics more carefully because the units do not rush like "Fast Forward Benny Hill" to cover your mistakes.
Various changes to morale and battle mechanics create more lasting battles which are not only an enjoyable experience, due to the fantastic combat animations but also they are very challenging, because the AI benefits from carefully made modding techniques.
Projectiles are not homing to the targets but more realistically spread and can miss. Their lethality and accuracy are not as high as in vanilla in a few words.
Increased unit sizes for epic battles, if the user wants them.
Removed all the insane cheats for the CAI, which provided a "fake" challenge and kept a moderate handicap system that reflects better the actual difficulty level.
Diplomacy and campaign AI have been improved significantly to cover the gap of the reduced handicaps. For example the AI invades with large armies consisted of more samurai than archers (vanilla problem), uses ships better, allies are more trustworthy, realm divide effect is reduced so that the clans do not berserk against you, and so on.
Autocalculation of battles works better.
Fortifications have more garrison troops, so now the major AI clans can survive and become very powerful opponents, like the Oda clan.
The economy system is slightly improved to encourage the recruitment of larger armies for both the AI and human player.
Upgrade points for characters are increased from 2 to 3 for a better and quicker character creation.
Several annoying things, for the majority of players, are removed like the projectile trails (laser trails) and the Horo (Balloon). The removal of laser trails in combination with the reduced speeds brings a significant FPS increase.
Increased army and navy control radius in the campaign map for a more strategic positioning system. An army cannot so easily pass by another army and has to fight it, or several small armies can trap other armies.
Better naval battles because now ships turn and accelerate not like motorships but like wooden vessels full of soldiers and also there are many other factors affecting the naval battles including the more realistic projectiles.
Ships have much more movement points that makes AI to launch powerful naval invasions.
Clans have more diversity for their special units, so the AI makes the right choice and builds characteristic armies, for example the Takeda raise powerful cavalry, the Date a lot of No-Dachi, Shimazu their deadly Katana, etc.
