Introduced in Smackdown vs. Raw 2006, General Manager mode was a surprisingly fun addition to the series. Players took control of a faction, managed the roster, and tried to beat out competitors in ratings.
The mode is commonly compared to Extreme Warfare Revenge, a popular text-based wrestling business simulation. The mode begged for expansion, but it only lasted two games, cut out in time for Smackdown vs Raw 2008.
WWE has since introduced Universe Mode, but many fans say it's a poor substitute. It's also recently experienced a share of problems, such as data corruption. Your move, 2K Games.
