Xbox 360 Achievements sell more games

A study by Electronic Entertainment Design and Research has indicated that games with more Xbox 360 Achievements generate greater sales. The study also claims that those with online achievements sell 50% more copies than those without.
Of course this can all be explained by higher profile games having more attention lavished on them in all areas, thus making them better games that just so happen to have lots of achievement points. It seems there is more to it than that though, as games that announced their list before release were found to sell better than those who kept it secret.
We can probably also expect a lot more viral marketing, as games that incorporated achievement lists into their viral marketing saw a 50% increase in sales. Geoffrey Zatkin of EEDAR had this to say about their study:
“Our research shows that incentives such as Accomplishments impact sales choices such as which game title to buy and which platform to buy it on; they also extend the replayability of a title. Consumers want their games to include both variety and abundance of Accomplishments.”
