Boy, this question hurts.
For anyone above a certain age with kids below a certain age this isn’t a punishment or a challenge, this is A DREAM!! Heroes of might and magic 3, system shock 2, Anno (any version up to 1503), Morrowind, Civilization 3, Age of wonders shadow magic, Baldur’s gate 1 and 2…
Whenever my wife finds the time she goes to her room to play Morrowind. She just got a new laptop and the first thing I did was install OpenMW and copy her save file.
It goes without saying that you couldn’t finish any of those games in those 12 hours, except for System Shock 2.
It’s not reductive, it’s misrepresentative. A puzzle game is only a puzzle game as long as coming up with the solution is the main task. There are more than enough games where coming up with the right solution is not difficult, but performing it is.
Also the name puzzle game implies that there are designed puzzles. Any game where you have to make decisions in generated situations aren’t puzzle games. For example if you take a specific chess situation and ask which move would lead to check mate in x moves then that’s a chess puzzle. That doesn’t make the game of chess itself a puzzle.
