Features:
* No changes without historical rationale, gameplay balance, and consideration for AI decision making.
* Detailed AOR system that allows for multi-facted Imperial armies with represntative and unique line troops from many different regions.
* Changes to battle dynamics: movement speed, projectile ballistics, lethality, fatigue and morale to more closely match historical accounts and doctrine, while maintaining game balance and playability.
* Significantly reworked aspects of the happiness, research, income, building benefits, campaign income, and more. Balancing progress, happiness and industrialization will be much more challenging, and the better balanced buildings will help the CAI. You will have to make very hard choices.
* Dozens of new descriptive strings to communicate changes to unit types, remove non-period wording, and provide Line Infantry with the language appropriate translations of "Regiment of the Line", all based on proper descriptions pack originally from l33tl4m3r.
* Many land units subtly rebalanced and differentiated to more closely match historical accounts and doctrine. Descriptions updated.
* Changes to North American land combat units, inspired by Quixote's Imperial Splendor.
* Spanky's Realistic (and extremely well researched) Flags.
* Spanky's period loading screens, accompanied by lesser known period music by Corelli, Telemann, Bach and others.

* Navern's firing more visible firing arc.
* MechDonald's Smoke and Blood Light 1.8.

* Jingle_Bombs 7-Year War unit textures.
* Warhanomars' Pip-mod and Marble re-skin for the UI.
* TheStinger's slightly modified early-game campaign script.
