Sure, it’s based on Middle Earth, D-fish!
One caveat: the first edition, called LOTR Risk, does not include Gondor or Mordor. (Think of it as the Two Towers edition.) Some fans are teed off about this, but I would say the game plays well. The latest version, called LOTR Risk Trilogy Edition, includes those two regions, plus a third additional area (Horvath or something, to the south of Gondor & Mordor) for a total of nine regions of varying values.
Some of the extra-army (they are called battalions, rather than armies, while the entire force you command is your army) bonus amounts earned by playing adventure cards differ depending on whether the player is evil or good. It seems to based on whether the “power site” associated with the card lies in a territory generally considered more on the good side or evil side of the board.
