The Total War series is one of those that has set the bar when it comes to grand strategy and offer its players the somewhat unique, among grand strategy games, possibility of controlling their forces in tactical battles. Empire Total War is the fifth standalone game in the Total War series and, released in 2009, continues to evolve the series with an improved engine, a new regions like India and a move to the 18th century.
In ETW you are in control of one major faction of the early 18th century, free to pillage and conquer to your hearts desire. With more than a dozen playable factions and nothing to force you along a certain narrative it offers an awesome sandbox environment for your grand strategy aspirations.
Gameplay
Gameplay is split between a grand map where players interact with their towns, armies & navies and a tactical mode where armies clash on the battle map and players control the regiments of their army.
While on the grand map players must handle their nations national interests and ensure a steady flow of cash to pay for the development of settlements, upkeep of armies, and to raise new forces as necessary. Not to mention making sure your troops are where they will be needed, counter uprisings and basically keep everything under lid.
The tactical map is where the fighting happens, here you will lead your army to gallant victories and crushing defeats, all while having tons of fun.
In battles you have direct control of your armys regiments and issue orders as to where they should go, formations, when to attack or whether or not to fire missiles at will. This gives you a ton of options when finding the strategies that work for you, some more rewarding than others.
An important aspect of battles, that will influence your overall strategy, is that losses in battles carry over to the grand map. Thus if a unit were to lose the majority of their rank and file in an engagement, they will be at half strength in the next engagement until it can be reinforced.
My Most Humble Opinion
If you are even remotely interested in grand strategy games you need to get Empire Total War!
This game is a good time but has some unfixed bugs. Napoleon TW is the better version
