This reminds me of a time circa 2005 where "Sub OSes" were somewhat popular in the GameMaker community. Seems that given enough time someone will try to make an OS-like interface in a given game engine.

It was a great way to understand UI and usability paradigms beyond building game mechanics.

This definitely triggered some pleasant nostalgia for me.

Nice to see someone else who also remembers those.

I was the creator of Tiagix OS, AFAIK one of the first subOSes that actually had support for creating apps for it.

Learned a lot about GUI toolkits making it, since I had to implement one from scratch for it.

Do you have any material online on Tiagix OS? I can't seem to find anything from a quick Google search.

I think there's a build of an older version of it on the YoYoGames archive. The archive didn't save the screenshots that the original website had, sadly.

I also spent a long time working on a very large update which I might have archived somewhere locally but never shared it online.

Looks like there's still some activity in the "scene" all these years later.

Also there are some in browser operating system as well, typically they have OS UI shell and applications. Unfortunately I forgot their names.
