This was the main reason I bought an X-Box, was to play KOTOR. This game is the RPG on the Box (which isn't saing much anyways) and the best RPG released on the Next Gen Systems (GC, PS2, XB) and I will tell you why.
Gameplay (10) More exciting than any Final Fantasy game because you can move around and it's real time. Instead of just watching yourself get slaughtered you can run away and heal, then quickly get back into the action. Switching characters is seamless and easy as well. Great and exciting gameplay.
Graphics (10) The best Graphics I have seen thus far on the Box. This game has the best looking Cut Scenes and the best looking game time graphics of any game I have ever seen. No problems here.
Story (10) All I will say is the story line is not Linear and you make it what you want it to be basically because YOU choose on being GOOD or EVIL.
Sound (10) It's a Star Wars game, of course the sound effects and music is going to be top notch!
Replayability (8) This game will get old, but you will want to beat this game atleast twice, once for good, and once for evil. No Multiplayer.
Fun Factor (10) Believe me, you will have a blast palying this game. (Especially the Dark Side) You get many choices in this game for good and evil.
Finishing Touches - If you own an X-Box, why the heck don't you already own KOTOR!?
Overall - 9.7
