I worked hard on the droideka. Just because one thing looks similar to another doesn't mean I stole it. A droideka looks like a droideka. I brown townyzed the Droideka in Battlefront II, and used some youtube videos of droidekas to model it. I'm not good at making models from pictures because I can't interact with it. Videos show more angles and allow multiple views, and I can see every angle in Battlefront II simply because I have control over the camera.
