I'll give you one other category - off-road focused SUVs (Wranglers, Broncos, etc...)
It looks like it changed last year, but the UK. The law was previously that pedestrians in a crosswalk should wait until it was clear to start crossing, as opposed to cars should stop if someone is waiting to cross.
In the case of Steam that could easily be implemented by Steam with no blockchain involved since everything is tied to your account.
If you know that, then you would know it wasn't written from scratch...
Sometimes the most complex problems require simple solutions
The Turtles collection is a great example of this. Rewind, save states, even some debug mode stuff. Well worth it.
I think part of it is a discovery problem. Which, I know, I don't want some algorithm telling me what content to look at, but it's tough to find all the stuff I'm interested in just by searching.
That's just not what really happens though. Look at Robert Broglia's emulators. They are open source and paid, and are some of the most popular paid emulators on the play store despite the fact that people could just download the source from his site and compile them.
You don't need to know how to code certainly. If you choose a "fire and forget" distro like Ubuntu, Linux Mint, etc... the only thing you would really run into any challenge with is running Windows software. Games are pretty well handled by Steam/Proton at this point, but other Windows software like, say, Word or the Adobe suite can be a challenge. If you're okay with using alternatives (libreoffice, darktable, gimp) you'll be fine.
To be honest it goes beyond that. The steam input customization is major. Like the fact that I can take a mouse and keyboard action RPG and assign the left stick to move around just like it had controller support.
Sweet tea can have as much sugar as soda. You would need to add 10-15 sugar packets to a single glass of iced tea to have the equivalent amount of sugar.
That plan sounds double-plus-ungood
