Solving a difficult puzzle isn't satisfactory enough for you?
If I said "no", would that be asking for too much? I think if someone finds if they aren't being satisfied with what's given to them when completing multiple challenges, it's perfectly fine to think that they aren't being properly rewarded for the work they put in.
I think The Witness is a special game for it's fundamental approach to challenge and reward, but you can't say I'm wrong when I say it's discouraging to face complicated puzzle followed by an ever more complicated puzzle. It keeps me going for sure, but it absolutely makes me want to take a breath and say, "here we go again" after the brief satisfaction of the previous puzzle fades.
I find that exhilarating on the contrary. That's the point of puzzle games. In this game it is especially well done since you're always given the keys to understand what you're supposed to do. It's just a matter of seeing it, and doubting your previous assessment.
Which is a great thing to do even in your life.
And that's the exact counterpoint to the way I described feeling after a puzzle. It's totally valid and I understand it, and it certainly applies to me at times, it just doesn't feel that way a lot of the time; but does that make what I feel after doing a set of puzzles wrong and therefore I should go play a different game that rewards me quicker? I say no but other people tend to take my experience and judge it as "You're just playing the wrong game if that's what you're feeling" or "Video games have taught me the wrong way to feel rewarded"
