Disclaimer: I do not know anything about KenKen puzzles (apparently it was/is popular especially in Japan…). Also in Japan the puzzle culture is on an absolutely different level, it’s hard to describe, but puzzle-solving even has a separate word for it: "nazotoki" :)

I’m not into videogames much myself. I was wondering if there is something I might actually like; so far city/civilization-building was the only thing that felt kinda ok-ish. I'm not sure whether there are good elegant puzzle games out there: everyone recommends Jonathan Blow's The Witness as some masterpiece, but despite all his philosophy and deep talks, after less than an hour I felt it was basically one puzzle with steadily increasing difficulty... given what I expected from his talks I was kinda disappointed.

For some reason your reply is associated in my head with a very very heavy book (it was hard to read... on physical level): Being Mortal by Atul Gawande. I sometimes have strange associations like that where it’s very hard to pinpoint the exact connection...
