All of it was amazing. From a non-partial point of view, the Live action universe was the most important as that is where it all began. But as for what is the most important part for me personally, I would say the video games, the movies, and near 'n' dear to my heart the animated universe. Had my brother never picked up Battlefront II on our old PS2 in the earlier 2000's, we would have never became a fan. Though the original LEGO Star Wars is what I found myself spending a lot of my time playing, later seeing the movies a year or two later, and what really was important to me was watching The Clone Wars on Cartoon Network as a kid. I remember sitting there, waiting for the premiere and being so excited when the opening appeared, seeing Yoda, the Clones, Ventress, and Dooku. The animated series and games were what left the biggest impact on me, personally, and are quite important to me. They were a huge part of my childhood.
