well I started playing it, and the graphics are amazing compared to wc3. You can also go under ground and above ground which is an interesting feature. Other then that it seems to be a copy of wc3. IMO I think Warcraft 3 is a better game. I just think it has a better flow to it. It may be just because I am more used to it. My friend down the street loves this game. He thinks it is better then WC3 by a long shot. So I guess it is a good game but it all depends on your preferences.
Right now I am trying out Age of Mythology and it is very interesting. I started a topic on it.
