A PlayStation.com survey (via Evil Avatar) suggests Sony might be ready to make the God of War 3 Collector's Edition really worth the extra cash. The survey asks users to rate what items would be most desirable as extras, and among the listed items we see "God of War and God of War II on Blu-ray." That popping sound you hear is your mind being blown.
Other potential extras include a soundtrack, graphic novel, art book, exclusive DLC, and featurettes. The survey also asks if players would be most interested in a Kratos statue, keychain, necklace, or t-shirt. All of the potential goodies sound nice and all, but next to two full games it's pretty hard to compare. Take the survey and let your voice be heard. Just be warned, if you vote for anything above the inclusion of the two previous games, and they're not in the box, we're all blaming you.
