Passage: While Gothic II received very high reviews in the German press, it did not fare that well in North America, where the game received "generally favorable reviews" according to the review aggregation website Metacritic.One of the reasons for the overall worse reviews were the graphics. The translation of the script and the voice acting in the English version were also criticized, and were felt by critics to be out of place and poorer than in the German version. Much of the voice acting criticism falls upon the change in the voice for the character Diego.Douglas L. Erickson of Computer Games Magazine called Gothic II "a role-playing experience in the truest sense." He summarized, "Rarely inconsistent, often frustrating, and always flexible, the world of Gothic II is, for lack of a more appropriate term, the most believable virtual place you can visit."Gothic II won PC Gamer US's 2003 "Best Roleplaying Game" award. The editors called it "a return to the roots of classic fantasy roleplaying on the PC" and noted its "beautifully detailed nonlinear 3D world". It was also nominated for RPG Vault's "RPG of the Year", "Outstanding Achievement in Music" and "Outstanding Achievement in Sound" awards, all of which went to Star Wars: Knights of the Old Republic.
