This puzzle is the Towers of Hanoi with three disks. A, B, and C are the pegs, and the positions from left to right are the disks; the lines connect positions that are valid to move between.
The initial puzzle is probably the Towers of Hanoi with more disks - the area needed to draw the diagram is quadrupled with every new disk added, so a larger diagram ...

After a long time in space I started to forget what N and E stand for on Earth. Well, now it's clear to me: East and North are directions. The first time I tried to get through those Space Grids, I mixed them up and also tried to take clues from the spectrum... Oops, let me get the spoiler glasses on. I might talk ...
This is something to do with
Specifically (with thanks to @GentlePurpleRain for help coming up with this):
This fits with most of what your rival is saying, as follows (with help from the OP for one or two lines):
Ah, interesting! But I don't get how this one is supposed to work; it obviously looks too short.
Hmm...a CD maybe?
Silence? What could mean ...
I have noticed that in the first image,
Solving picture 2 using the rules of the game yin-yang (suggested by @edderiofer) gives the unique solution
Now, adding shapes to the second image using the rule discovered in the first gives the new image
I actually think it is the number of sides of the shapes rather than the shapes themselves that matter - we ...
If we assume that one of the puzzles is a sudoku, we are left with only four possible grid constructions because the last two pieces can not be next to each other and have to form the diagonal. I tried slitherlink as the second puzzle which gave a unique solution for only one of those grids. In that grid the three corners with numbers can be solved ...

I solved the Sudoku, then learned from the other answers here, that the next step is to solve a Yajilin, a puzzle type I haven't heard of before. As these both steps are already covered in the other answers, I only give the combined solution here:
Now the last step is

but after the square marked 16, Robert's got this (image courtesy of OP)
and we can now see why Robert is distressed:

My initial set of rules:
That was close. Upon some solving, I realised that:
That solves all the outer puzzles, with a couple of tricks to help simplify:
To solve the centre puzzle:
It looks like a version of the Prisoner's Dilemma. You're player 2, and the choice is either to Cooperate or to Defect, after which player 1 will make their choice on the second level of the tree.
If you both cooperate, you get the best overall outcome ("only" 2 points lost total). But a defector to a cooperator gets a better outcome for themself (...

Let me try a different approach.
There is one red square in each row and column (fact). That provides us with a free pairwise collocation on rows and columns, or: on the letters written one the up and on the left. This collocations for the first three images (yes, that is a lot of examples!) give you:
Drawing a line through letters is convenient, if we ...
