It's Risk!
Let's hit up the graphics...they're decent for what they have to work with and they enhance the game slightly with some corny interaction between the characters. On to game play...I think it plays well. If you're used to playing the board games you know how long a game can take, but here you can get through a game rather quickly which is fun if you don't have the time otherwise.
All in all I think Risk is worth owning if you're a fan, but there are several different ways to play Risk-like games online that are either cheaper or free. This is a cool way to play against the computer though and it'll show people you like the game if it's in your collection.
