What is your comfort activity (like comfort food)?
Mine is playing AOE2 in easiest (or standard if I want a bit of challenge) mode against 3 bots. I just build my economy, wall up (and laugh at the enemy soldiers attacking my walls in vain), reach imperial age and attack once my army reaches the population limit. I also send 104 in the chat so they don't surrender and I can enjoy razing their all buildings one by one. If any of them builds a castle, even more fun. A build a trebuchet and watch it raze the castle from a safe distance. If there is sea, after I am done with the land, I build 3 docks, do research and build a navy and hunt down ships around the unxplored sea. It is fun, satisfying and relaxing.
Factorio. Hands down. I have a few other games that I self-soothe with, mostly colony builders, idle games, or automation games, but Factorio is my go-to when I get into a bad headspace. To the point that my "end of world" plan includes immediately scraping the entire mod database to a portable hard drive, along with Rimworld's entire collection. If I have those + my Steam Deck, I feel like I would be able to manage in a full social collapse and Mad Max-esque world. I know how to build a variety of generators and the proliferation of solar panels has made post-collapse planning a lot easier.
I am also regularly doing mirror backups of the whole of Wikipedia. I am thinking of adding Wikihow to that automated task. Wikipedia is only like 20GB for the aggregate knowledge of most of humanity, so well worth keeping for research after the internet dies.
Assuming you are talking about Wikipedia here. It is pretty straightforward at the most basic level. So much so in fact that Wikipedia has a page dedicated to it.
I use Python on a scheduled job on my Windows PC to update it every so often, but you could setup a cron job in any job scheduling software for whatever OS you are using to do it. There are even ways to do it on your phone. I am only doing text currently, but I will likely so images and videos for certain knowledge domains in the future. Articles in fields of Math and Engineering rely heavily on them for illustrating (duh) the concepts.
If you are talking about the emergency download of all of the mods for Factorio and Rimworld, that I still need to research some. I was planning on just using the check all and download inside Factorio's in-built mod manager. Rimworld I will probably have to see if an api exists for the Steam Workshop and build off that.
