Gamasutra looks at Xbox 360 Gamerscore and game completion statistics in search of a reason why some players stop playing games in their library.
According to the feature, a game's overall difficulty is the biggest culprit from discouraging players from completing a game. Using data of 14,000 players regularly surveyed provided by Microsoft and the top 13 Xbox Live titles in 2008, it was concluded the group unlocked less than half of the possible Gamerscore on average. Gamasutra notes that the selected users in the survey tend to be more hardcore than the average player, so overall completion rates are expected to be even lower.
Another point of the study was to determine the average completion of a game's campaign mode. Using data of games that award campaign completion Achievements, it was determined that only 30 percent of the surveyed group did not play games until the end. Gamasutra theorizes that the reason so many gamers neglect a game's campaign is due to frustration. Having experienced the -- sadly, often horrific -- world of Xbox Live, we'd also guess many of the hardcore gamers examined skipped the campaign in favor of pwnin' n00bs online.
