of 140,000 copies in its first week at retail in Japan, reaching number one in the charts. Almost 80% of the initial Japanese shipment was sold within two days. These figures compare favorably with Ico, which was well received by critics but failed to sell a significant number of units. The game was placed on Sony's list of Greatest Hits titles on August 6, 2006. Critical response Shadow of the Colossus received critical acclaim, with an average critic score of 91% at GameRankings, making it the 11th-highest rated game of 2005. The game received strong reviews from publications such as the Japanese magazine Famitsu, who rated the game 37/40, the UK-based Edge, who awarded an 8/10, and Electronic Gaming Monthly, who granted 8.8/10. GameSpot's review gave it an 8.7, commenting that "the game's aesthetic presentation is unparalleled, by any standard", while multimedia website IGN hailed the game as "an amazing experience" and "an absolute must-have title", rating it 9.7/10.
