Since we're stuck at home, I'm sure a lot of people who aren't usually gamers are looking for new ways to alleviate their boredom, so I compiled a short list of game recommendations for people who never normally play video games:
Journey is tied as my favorite game ever. It is stunningly beautiful and serene, and the soundtrack was the first game soundtrack ever to be nominated for a Grammy. It was originally a console game, but is also available on PC and Mac now (though I don't know what the system requirements are). It's mechanically simple and intuitive, and should be enjoyable to gamers of any (or no) skill level.
Sky: Children of Light is a phone game made by the same studio that made Journey. I haven't played it, but my wife loves it.
Monument Valley is another phone game, a puzzler inspired by the art of M. C. Escher. It's very beautiful, very beginner friendly, and challenges your ability to reason in three dimensions.
Dear Esther is a haunting (if somewhat depressing) character study. Very pretty, somewhat abstract, but doesn't require any particular skill with a controller.
The Stanley Parable is a darkly comic commentary on either gaming or modern society in general, depending on your interpretation.
All of the above have only minimal mechanical challenges; that is, they don't require a lot of speed or precision with a controller or keyboard.
If you're up for something with more of a mechanical challenge, here are a few more recommendations:
Katamari Damacy is weird, whimsical, and delightful, and while it does require some precise control at some points, the learning curve is fairly gentle and you don't have to be particularly good to find enjoyment. Like Journey, it was originally a console game, but is now available on PC (and I think Mac as well, but don't hold me to that).
It also has a phenomenal soundtrack -- I suspect about half the game's dev budget went to the audio department.
Tetris is a classic which has stood the test of time. You can learn how to play in under a minute, and then spend years improving your technique. There are versions of it for pretty much every platform imaginable; heck, I wouldn't be surprised if there's a version that can run on your toaster.
If you've never played a platformer but want to try one, honestly the best place to start is with the original Super Mario Bros, which you can play for free online here:

While the game is 34 years old, the learning curve was crafted with astonishing care, and even to this day is often held up as an example of brilliant and intuitive level design. Later levels can get brutally difficult, but the game does an excellent job of gradually ramping up to that point.
Civilization is a series of strategy games. The whole series is excellent, though I have a special soft spot for Civ 4; its main menu theme, Baba Yetu, was the first piece of video game music ever to win a grammy.
Chrono Trigger is a Japanese RPG widely considered to be among the greatest games ever made, with one of the greatest soundtracks in the history of games. There is a mobile version, as well as a mac/PC version.
Portal is a first-person puzzler for PC/Mac, which is loads of fun, easy to get into, and has some of the funniest dark humor I've ever heard in a game.
