Everything else is contained within the game. It could be real or it may not be
You do realize that the Matrix was based on an ultimate reality, right? That outside of the matrix was a true reality. And since I do believe that God is existence and we share in His existence, His existence is the ultimate reality. But that in no way negates the reality of our current existence as we share in His in a different way.
The thing about the Matrix is they found a way to actually see and experience that other reality. We don't have that in a factual way. We have ideas that have been corrupted through religion that we use to try and explain God and teach the masses how to behave but I see that as man made. Like those in the matrix that have not yet taken the pill, the people suspect there is more to life but don't have the ability to really know what's real and what isn't. Do you think the things happening in the Matrix are absolute reality or subjective perceptions of reality?
I wouldn't waste my time thinking about an alternate reality to be honest. Nothing good can come from stealing time from the present. It's better for me to enjoy the right things, the right way for the right reasons. Life's a journey and I have already won the cosmic lottery.
According to the story being in the Matrix was the alternate reality. Being used for power generation was the reality. Being subjective involves bias. I'm not sure if bias played a part in the Matrix or at least not a big part anyway. So not sure how to answer your question about subjective perceptions of reality. Man's problem isn't that he is living in an alternate reality, man's problem is rationalizing wrong as right.
What it Gods realty is the Real Reality? An eternal reality based in infinity which we humans in this time can not yet understand. And what if our reality is a fragment of the real? A finite linear perception.
I agree, no point in wasting too much time pondering this as the more important is the here and now... I just like dropping food for thought.
I don't waste time thinking about the destination. Giving thanks and praise to God is a different story. That has practical benefits beyond imagine.
My perception of God is that God is infinite logic, infinite truth, infinite intelligence, infinite wisdom, infinite knowledge, infinite love, infinite patience, infinite justice, infinite mercy, infinite kindness and infinite goodness. I am not saying God has those attributes. I am saying God is those attributes. Such that mind has always existed: that this is a life‑breeding universe because the constant presence of mind made it so and imbued his creation with His attributes.
Would that also mean that God is infinite pain, and infinite evil and infinite sadness?
Then it begs the question of whether good and evil actually exist in a significant way.
Ahhh.... now we get into it.
Those are all negations. For example, cold is the absence of heat, darkness is the absence of light, and evil is the absence of good.
But the direction you are heading is into the inscrutable ways of God. Here is what Maimonides said on the subject...
[MEN frequently think that the evils in the world are more numerous than the good things, that just isn't the case. It must be admitted as a fact that it cannot be said of God that He directly creates evil, or He has the direct intention to produce evil; this is impossible His works are all perfectly good. He only produces existence, and all existence is good. God is perfect goodness, and that all that comes from Him is absolutely good. Consequently the true work of God is all good, since it is existence. ALL the great evils which men cause to each other because of certain intentions, desires, opinions, or religious principles, are likewise due to non-existence, because they originate in ignorance, which is absence of wisdom. The numerous evils to which individual persons are exposed are due to the defects existing in the persons themselves. We suffer from the evils which we, by our own free will, inflict on ourselves and ascribe them to God, who is far from being connected with them. Man himself is the author of this class of evils.]
