Possibly one of the most underrated games of its genre.
The main part is the campaign where you take your nation to dominate europe, It begins in 1910 and ends in 1950 and depending on what country you are, historical events can happen good and bad, for example if your germany in 1923 then youll get the "Beer hall putsch" event where if you dont supress it The Tyrant (Hitler) will rise to power. Or if for example your Britain and your at war in 1916 youll get a historic event saying that you need to start a new offensive and hire a new general (Douglas Haig at the somme) and of course many more.
Theres many histoircal figures you can have in your cabinent, you get a discount if their from your selected country but you can pick any characters provided you have enough education- theres generals,scientists, humanitarians, ministers and spies; all of which have special and unique abilitys. , the two resources are Industry and education, Industry is for buiding , guns , tanks and planes while education is for research and hiring characters and the other is living standards which helps your population and economy to grow.
The comabt is great and the buildings collapse very realistically, perhaps the pathfinding can be a little flawed but nevertheless the graphics and the troop detail surpass this (and also i think theres a patch)
Overall this is a great game and i highly recommend it to anyone who likes RTS/mangement or history related games.
