In the movies there was night on Tatooine

Why doesn't Tatooine or other planets have a day/night cycle?

because although it's a cool feature it is not vital to launch with.

For what purpose? Yes some other MMOs have it, but I've yet to see any point to it. WoW only had it because Warcraft 3 had a genuine game mechanic built around it.

The other thing about night in the desert is that it really is very very very dark. Not merely 'a bit dim'.

I too would like day/night cycles on the planets.

I wouldn't put it in my top 500 nit-pick improvements, but yeah.

The only reason I've figured they haven't done night skies, is how incredible complex it would be to correctly display the Star Wars galaxy from different planets in the night's sky.

To paraphrase your statement, "because they can still take your money without it".

And they can take your money without :

No guild support
No LFG
No UI addons, combat logs, target of target
Linear Planets "follow the paths"
No World exploration or PvP possible
Loading screens
Broken combat system
Broken game client with low res textures and no antialising, having to run as administrator spying on all the running processes on your machine (who knows why)
Cannot fly over any planets not because they never flew in Starwars but because the planets are small, cheap and not "flyable" not 3D

Apologies if I have forgotten anything.

I would like having the cycles, but the only time I think about it them when people here complain about not having them. I don't really think about them at all when playing.

In the movies, Leia was in a bikini.

I checked my box 3 times, and still haven't found her.

I'm gonna sue.

Too much work and the devs are too lazy and they don't care about you, only your money. Immersion and a living world was not in their plan, only story.

This game is just garbage.. not even alpha. It is almost like MUD. Sucks...
