I'll counter that, I read a couple of Go books and I'm still not clear of when the game ends or how you count points, go is very elegant but let's not pretend all its rules are simple and clear.
The game ends when both players pass. That's very simple and clear.
You score by counting the number of unoccupied points in your territory and adding the number of your opponent's stones you captured, + the "komi" that the second player gets to make up for going second (usually 6.5 for a full size board). (A common technique is to place all the stones you captured on empty points in your opponent's territory, so that you're subtracting the number of your captures from their territory). The only possible ambiguity there is around what constitutes territory; if you like then as a beginner you can just make the rule "unoccupied points in regions surrounded entirely by stones of your colour", which will make for a few tedious turns at the end where you fill in the last few gaps but won't change the scoring at all.
The rules are simple and clear – their consequences are not.
The game ends when both players have passed in succession. Each player may pass whenever they want. That's it. It's super clear. Figuring out when you can safely pass? That takes years of study. But essentially it is a strategic decision, not part of the rules. You can pass throughout the entire game, it would just be a really dumb strategy.
Regular players make counting points more advanced than it has to be in the interest of speed (similar to how mental maths tricks can be very advanced ways of computing simple sums or products).
The score is determined by the number of pieces you can put down on the board. That's it. (From this follows, of course, that empty intersection your opponent has solidly surrounded is probably not going to count toward your score because your opponent can kill whatever you try to play in there.)
