Just off the top of my head, Ross Scott on youtube (AccursedFarms) has plenty of videos on the subject. A few of them are tucked away in reviews but he now has a dedicated "dead game news" series.
These may not be games you'd want to play but the important message is that it's concerning that the biggest publishers (Ubisoft, EA etc.) can release stuff that will randomly die at some point in the future for no good reason and that they won't even release a patch or server software so you can play the product you paid them for.
It's a fun little thing but BEWARE! It's still a bit buggy and crashy* and rough around the edges. You can kinda see what Zep is going for but a lot of it is quite mysterious and there's little in the way of API docs (as-in, people are having to print all the global lua tables to figure out how to do stuff)
*Not as much as 0.1a but there's still kinks to be worked out for 0.1c.
I've always wondered what Japanese console style games would look like on the Amiga and whether it was underpowered or I just didn't like the design of most of it's games.
Bonk got a fab conversion by Factor 5 but they were wizards.
I agree that we need a new - less crufty - standard to replace HTML/CSS/JS but there's another point which I feel has been sorely missed in previous efforts.
I want a FUN standard. I want to make cool looking sites that are relatively scalable based on user hardware.
Alternatives like Gopher and Gemini never really scratched that itch due to how sterile they are.
I only know about this one because it was parodied at the end of a Ren and Stimpy episode (Ren Needs Help!) and I thought it was the funniest punchline I'd ever heard.
It's always a little disappointing to find out that something cool was actually referencing something else but knowing that the president actually said this helps dull it.
Bob Nystrom's Crafting Interpreters is generally well regarded these days although I'm unaware of any of the classic "so you want to build a programming language" texts.
Facebook, Twitter et al have entire office floors to deal with legal threats.
The UK police love to go after "soft" targets and there's no-one softer than someone who's life can immediately be ruined by arresting them and thus getting them fired due to missing work.
Edit: I now see you mean "host their own personal content" but the point still stands.
I'm very shocked that these were only discovered so recently (Well. If you consider the early 2000's to be "recent". I'd have assumed that we'd have found these out earlier)
I suppose that's why they were all the rage in childrens' books and museums around that time.
From what I can tell, there isn't even a version of Roblox Studio available. Scratch seems to work though.
