I really can't review this game properly, since I COULDN'T GET IT TO PLAY! Risk is one of the dreaded "Blue discs" that are almost impossible to get to play.
A blue disc has a blue backing on the underside (Where most games are silver like a mirror). I am sure that this is done for some reason... but I really don't know what it could be. Whatever, the reason... do NOT BUY blue disc games.... I have owned two and neither have played on my Playstation (which is only a couple of years old).
So while other reviewers tell you about the gane, listen to my advice first, "This game may not even play on your PLaystation". Definitely rent the game before wasting the $$$ to see if the game will even work on your Playstation.
