Combat Upgrade - Sony community's name for the changes made to the entire character development process of
Star Wars: Galaxies an online MMORPG video game. This "Combat Upgrade" (nicknamed CU) led to a number of players demanding their money back for the expansion that included these changes. After a week or two of protests Sony offered refunds to anyone who asked for it. Many
player towns became ghost towns due to the reaction of long term players who decided to depart en masse.
The
Star Wars: Galaxies game is often referred to as "pre-CU" or "post-CU".
