On December 17, 2009 on the European PlayStation Blog, it was announced that God of War Collection will be included in the God of War III: Ultimate Trilogy Edition. This "Ultimate Trilogy Edition" was released in limited quantities in conjunction with God of War III (March 18, 2010 in Australia and New Zealand and March 19, 2010 in Europe). 
The Ultimate Collection was released in Japan as a standalone on March 18, 2010 and was published by Capcom. A God of War III Trilogy Edition which included God of War III and God of War Collection was also released on March 25, 2010. The game was released in Australia on April 29, 2010. and in the UK on April 30, 2010.
The original God of War and God of War II were ported by Bluepoint Games and use the features of the PlayStation 3, including high-definition resolutions (720p), anti-aliased graphics locked in at 60 frames per second and Trophies. The port was derived from feedback of fans of the series and was viewed as a means of introducing new players to the series prior to the release of God of War III.
In a PlayStation Blog post on September 23, 2009, it was revealed that the God of War III game demo from E3 2009 is included. The official gameplay trailer was unveiled on October 16, 2009. The trailer was shown in PlayStation Home's virtual theater and as an advertising poster on the side of the virtual mall.
There are a total of 71 trophies between the two games - 36 for God of War and 35 for God of War II - including a platinum trophy for each game.
From November 24, 2009, the God of War team began a sweepstakes in celebration of the release of God of War Collection. The grand prize was an autographed "Gold" disc (a first pressing of the game created when assets were finalized and reached "Gold" status), exclusive artwork created and signed by a God of War team member, a Limited Edition Kratos T-shirt, and a never before released Limited Edition 10" Figurine of Kratos. First place prize was a copy of God of War Collection signed by the Development Team. Winners were announced on the PlayStation Blog and on God of War.com on December 24, 2009.
Due to the success of the God of War Collection, Sony has ordered new titles to receive similar treatment under a new brand of "Classics HD". The first series to receive a "Classics HD" release will be The Sly Collection.
