Many of the reviewers admit that they have not read Ms. Lawrence’s book.

As one Amazon user put it: “I know all about this book but have never fully read it. Why? Due to the overwhelming backlash, I have no choice but to agree with the 1 star ratings. The rumors are rampant that this book was poorly written and poorly researched. So without verifying the contents myself  I give it a 1 star. Good thing video games aren’t judged in this manner  whew!!!”

On Friday “The Cult of Perfection” was ranked the 346,106th best-selling book on Amazon. Mass Effect, by contrast, has been a hit, selling more than 1.6 million copies since November. An Amazon spokeswoman said the site would soon begin to remove reviews written by users who had clearly not read the book.

In an interview on Friday, Ms. Lawrence said that since the controversy over her remarks erupted she had watched someone play the game for about two and a half hours. “I recognize that I misspoke,” she said. “I really regret saying that, and now that I’ve seen the game and seen the sex scenes it’s kind of a joke.

“Before the show I had asked somebody about what they had heard, and they had said it’s like pornography,” she added. “But it’s not like pornography. I’ve seen episodes of ‘Lost’ that are more sexually explicit.”

Electronic Arts, the giant publisher that owns Mass Effect, has asked Fox News for a correction. A Fox News spokesman would say only that Electronic Arts had been offered a chance to appear on the channel. An Electronic Arts spokesman said the company had not yet decided whether to accept the offer.

By telephone from Edmonton, Alberta, Ray Muzyka, the medical doctor who is chief executive of BioWare, the Electronic Arts studio that made Mass Effect, said: “We’re hurt. We believe in video games as an art form, and on behalf of the 120 people who poured their blood and tears into this game over three years, we’re just really hurt that someone would misrepresent the game without even playing it. All we can hope for is that people who actually play our games will see the truth.”
