That might explain why Sith Lords dress like Medieval-Based fantasy villain like from Lord of the Rings, Dungeons and Dragons, and World of Warcraft, etc. Those huge black armored clothing with spikes are somewhat cliche. No offense, they're cool.
That brings to me to another discussion. I love
Star Trek even more that
Star Wars, I find
Star Trek more relatable to Real-Life, in fact, it take place in our Milky Galaxy. It sort of give out of happy vibe where Humans in the future on planet Earth is more 'socially-evolved,' people learned to become peaceful, moral, and tolerant, and no more greed, poverty, and illnesses and suffering on Earth. Well, at least most people on other places, and there are still war in the galaxy when it comes to hostile alien groups.
As you know, life in Star Wars Galaxy is opposite of perfect, including the neverending struggle between the Light Side and Dark Side of the Force.
I think
Star Trek act as a reminder to fans to learn from their Human past mistakes in history and put aside their differences and pride for the better.
During the Cold War on Earth, super-powerful nations: US and the Soviet Union, were manipulating the politics other underdeveloped countries, creating puppet governments to be sympathetic to either side; now and back then, the results are bad. In
Star Trek, there is 'the' United Federation of Planets' code "The Prime Directive." One of main UFP's policy is not to interfere the affairs of underdeveloped or primitive cultures on other planets; preserve to let their cultures independently flourish.
I guess the author, Gene Roddenberry, based his work from the Cold War and his ideas what people consider 'liberal'.

But that still doesn't explain why some spaceships can fly faster than others between franchises. I mean, shouldn't the physics between franchise be the same? Because it's physics?
