Kinect creative director Kudo Tsunoda said that the project has been in the works since before Kinect's reveal in June 2009, and that it was keen to "take the time to do it right".
"Certainly it's been in development before Kinect launched, and we had stuff on it when Kinect was first announced in E3 2009," Tsunoda told Digital Spy.
"I think Star Wars is such a huge IP, and when you take on the challenge of really wanting to deliver all these iconic Star Wars moments into one experience it's a thing you want to take the time to do right, and you want to put that level of quality on that will make it pop for all different Star Wars fans.
"It's been going on long before Kinect launched, and obviously before we announced Kinect as we had stuff on it there, it's just we put the right amount of time in to make sure this was a Star Wars experience with Kinect that all Star Wars fans would love."
Tsunoda added that the game's original vision was relatively uncompromised since its conception, with time spent on polishing the final product.
"The good thing was that we didn't have to compromise the original product that much at all. I think it's great working with LucasArts because they understand how to bring Star Wars to life in a way that's super compelling for their consumers," he said.
"Something that we worked really hard on was bringing huge Star Wars fans as part of our development team, so everyone who is working on the development team are huge Star Wars fans as well, so I think from the beginning we had a clear vision on what we wanted to deliver to Star Wars fans."
He added: "We were able to do so much of that with Kinect, and with what's possible on the Xbox 360, that really we didn't have to change our vision of what we wanted to do from the get-go much at all. And really, a lot of the time wasn't spent redoing things from our original vision, as much as making sure we put the polish and quality time into the experience so that every little bit of it shines for people."
The title was originally planned for a holiday 2011 reveal before it was delayed.
Kinect Star Wars is available exclusively on Xbox 360 from today worldwide alongside a special themed R2D2 console.
