This is a surprisingly fun version of Risk, though I don't care for the subject. Most people who simply like the original Star Wars trilogy will be surprised by the unfamiliarity of most of the areas under dispute - I certainly didn't know, nor could pronounce, most of it. I rarely got anybody to play this game, thanks to the theme and board, but the actual game plays well.
I probably can't tell you much about Risk that you don't already know. I just wanted to add that this edition is one of my favorites first off because of the Star Wars licensing. It is certainly cool to be able to play as your favorite Star Wars faction. The board is also very cool so look up a picture of it if you're thinking about buying a Risk game!
