In 2006, a very small "guinea pig" group of about five dedicated LEGO fans were invited to be a part of LEGO Universe's development. This group formed a team, with Eric Kingsley becoming the head of the group, which is now commonly called the A Team, or Alpha Team. At the time, the LUPs were limited to the use of LDraw and LEGO Digital Designer as tools for their development, though this was expanded later on. Along the course of time, a few fans left the program. But some remain, including the original five members, who created MoonBase.
