The Similarities Between Halo and Star Wars

This is not an exhaustive list. And I'm not saying the franchises are the same or anything. They just happen to be similar in some aspects.
Some key differences:
The overall plot for Halo and for Star Wars is almost completely different. The Covenant and the Empire are only comparable insofar as they are both totalitarian. The Halo rings and the Death Star are not even on the same order of magnitude when it comes to destructive potential.
Halo takes place in our galaxy and includes Earth; Star Wars takes place long ago in a galaxy considerably far away.
The three Halo entries that came after the original trilogy are not connected to each other at all. One is an RTS spin-off set 20 years before the originals. It was not made by the same people who made the other games. The next takes place during the events of the second game. The last one took place right before the first game. For Star Wars, the three films following the originals formed their own trilogy.
For Halo, the developers left the franchise to make something else. For Star Wars, the creators sold the franchise.
Cortana didn’t technically die like Han Solo did. But the good side of her was lost, while the rampancy side remained.
Remakes, remasters, and re-releases have been handled vastly differently. Halo has had only a few while Star Wars rereleases are basically a meme at this point, even spawning the Honest Trailer RUclips series.
The Halo TV series are more like mini-series and did not see anywhere the amount of success of the Star Wars TV shows.
Star Wars has had two spin-off movies since being sold to Disney. Halo has had three spin-off games since Bungie left, and one of them was a sequel to a previous spin-off.
Halo is a harder sci-fi than Star Wars.
And probably the most important difference- Disney wiped away the extended universe canon, while 343 Industries did not and has fully embraced it.
