If TFU had followed to the letter everything that the book portrayed, TFU you would have been a much better game. The romance between Juno and Starkiller was in more depth, Juno knew a lot more information then you previously thought. Alot more humourous moments. Even the battles sound better.
*Spoilers* For example on the fight on Felucia between the Bull Rancor anyone whos just played the game just saw Galen force pull him into the ground. Well instead of that lame ass action, Galen actually jumps into the mouth of the rancor, force electrocutes within because his lightsaber wasn't doing crap to the outside of the rancor and he used force repulse and blows up the rancor's head with force repulse and after he comes off he's literally covered head to toe with rancor blood. How awesome does that sound?
And lol funny moment even for SK. He tells Juno " Don't be alarmed when you see me. It's only superficial." And she says "Whats only superficial?" And he shows himself to her and hes covered all over the place with blood from the rancor. Ok well just wanted to let you know because I found out alot and there is one thing for sure. The story of the book was so much richer than the game's story.
