Legend says that the children of George Lucas, big LEGO fans, requested the Star Wars LEGO license. Legend also states that Lucas defers to his children's judgement on the suitability of these licensed sets, as well as their adherance to LucasArts standards.
The Star Wars LEGO license was launched in 1999 with the release of Star Wars Episode I: The Phantom Menace. LEGO has released new sets with each subsequent prequel, as well as sets based on the Classic Trilogy. The first sets were generally well-received, but some fans complained about the poor design of some vehicles, as well as the absence of enough unique minifigs (and far too many Qui-Gon and Jar Jar minifigs).
