I have left some older systems on for extended periods a few times because I was either somewhere I couldn’t save and didn’t want to lose a bunch of progress, or games that didn’t have save capabilities and I had to stop playing for some reason. Other than that, they always were and still do get turned off.
Not the OP but I have read the book. It’s very unique and the story is told in some pretty strange ways. Parts are written backwards, in code, in the margin of the pages, etc. I think it’s a great experience and I’m glad to see it on that table. I’ve never read anything else like it.
