He also states that good reviews barely have an effect on the sales of those games:
In other words, 93 percent of new IP fails in the marketplace," he explained on N'Gai Croal's Level Up. "So while the 90-plus review scores and armfuls of awards create the perception that titles like Psychonauts, Shadow of the Colossus, Okami and other great pieces of work were big successes...they were big financial disappointments and money losers."Source: ShackNews.
"The truth is that there is no correlation between review scores and commercial success," Allison wrote in a followup entry. "If there were, 'great' games Beyond Good & Evil, Ico, Okami, Psychonauts, Shadow of the Colossus, Freedom Fighters, Prey and Midway's own Psi-Ops would all have been multi-million unit sellers. The aforementioned games are all games that average review scores of nearly 90 percent out of 100, some even higher. The reality is none has sold more than 300,000 units at full price in the U.S. and a couple of these less than 250,000 units lifetime even with bargain pricing."
