Rise of Nations is such a **** game. I've always wondered why people liked it. The game is horrible, the gameplay.
All you really do is research stuff and mass 3 different types of units. And when you research a new technology, all your men suddenly turn into the more advanced unit! So during battle, your men will suddenly transform into more advanved units if you complete the research.
And all you really do in the game is send your army to attack. There's not much strategy, exept combining different types of units. Not even any unit micro.
