You should be able to answer that question more accurately than me. But I'm guessing you either expected to enjoy it or didn't have anything better to do.

An almighty being, however, should not have such needs.

Good point, yet whose to say, since the God of the Bible was said to be a jealous God which seems petty to me.

Bolded to get my point across better. The answer is: because it's awesome.

It's pretty simple. To bring light into the darkness. And by light I don't mean the countless balls of burning gas throughout the universe. Love needs souls to grow and free will needs conflict to mature. Everything exists for that purpose. God has no needs and we will never fathom the depth of God's complex motives. God saw darkness and brought light to it.

The difference is that you didn't know exactly how you would react to watching the movie each time.

Or, again, the problem is that you couldn't think of something better to do. An almighty being would never be in a scenario like that.

Why? World makes for a pretty good action movie sometimes.

GOLD!!!!!!!

OP: good question.

If God has no needs, why not settle with the "Darkness"? What would motivate such a decision?

And what would declare when the darkness should be replaced by light? If God has existed forever, why wait an infinite amount of years (somehow) until finally creating the universe? Why now?

Furthermore: Why create anything and watch as things happen when the final result can be achieved immediately?

Allah the Almighty, Who is the Maker of the universe and of all beings in it, created the universe for very significant purposes. Quran informs this as follows:

Not for (idle) sport did we create the heavens and the earth and all that is between. (Anbiyya Surah, 21:16)

Not without purpose did we create heaven and earth and all between (Sa Surah, 38:27)

All beings glorify and magnify the Exalted Creator with their languages. They fulfill the tasks with a pleasure and enthusiasm, which are assigned to them. For example, the sun, without falling behind even a second, moves around the orbit, which has been drawn for it. Rivers enthusiastically flow into seas. Animals, which have been given under the command of man, serve him with an absolute obedience.

Besides, if the universe had not been created, the never-ending perfection and beauty of the names and attributes of Allah Almighty would have never been known. This would have only been known by Allah (SWT). By manifesting the spiritual beauties of His names and attributes, Allah Almighty, besides beholding His own Beauty and Perfection on His own works, also wished to give a share to angels, man, and jinn from this honor and bestowal.

Regarding the question of whether to create the beings or not to, Allah (SWT) made His Divine preference for creation, and this preference has become an interminable mercy for all creatures. Or else it is unthinkable that Allahs, one of Whose names is Samed (everything is in need of Him but He is in need of nothing), creation of this universe stems from a necessity.

None of that explains why it is necessary to watch as his creation progress instead of just reaching the final result using his powers. As an almighty being, he knows where everything will end up and knows each and every decision that every being will make using their free wills.

Watching as everything happens just as he expected even before creating the universe is unnecessary.
