This is the best RTS game I've played so far and I could spend hours in front of the PC. It is cool that you can play with different ages and techologies, also you can choose huge maps though the came can become very long (in my case that's exactly the idea because I don't like rush). I really thank GOG.com for making this and other games available at a fair price. If publishers changed their market to make content accesible more people would be willing to buy, just like me some minutes ago.
