A beautifully re-created Age of Empires, only with guns and planes, but there's also the swords you know and love.
While it has it's similarities to Age of Empires, it also has it's differences. Rather than researching everything at the buildings that you need, which you still do most of, you can now build a library in your city within which to research the progression of the ages and the military, civic, commerce, and science research you need.
Also, now, as you progress through the ages, you have to gain new resources. for instance, when you get into the Classical Age (the second age) you must build mines near mountains and universities near cities, one to collect metal, a needed resource for all things military, and knowledge, needed for library research. and also, as soon as you hit the industrial age (age six) you need to start gathering oil. You don't just stick with the food, gold, wood, and rock you get in age of empires, in this you get food, gold, wood, metal, knowledge, and oil.
also, you can now get to the ages of stealth bombers and aircraft carriers we know today, not just the ancient sword-shield and bow-arrow method as used in age of empires
the strategy portion of the game is amazing. Rather than building transports at a dock, all you need is the dock, and if you order someone into the water, they just make their own transport in an instant. no population limit space wasted on transports. Also, speaking of population limits, you're not just limited to one citizen or military unit per one population space, now you can build three per population limit space, and these three stick together in one battalion, so an army of forty battalions would be like 120 men rather than just forty.
Again, if you like RTS games, BUY THIS NOW!!! It's simply amazing. You won't regret it. sometimes it can get confusing, so even if you're a really experienced fan of Age of Empires, do you know how do use submarines and planes? you should probably do the tutorial rather than rushing into a battle.
