The original project was something anybody could play, and as far as I know if you can find it you can still play it today, and you will be able to forever.
You can’t do that with TRA/OTOY now can you?
streaming-exclusivity is an extremely bad thing.

As for the minecraft stuff, trekcraft exists today, and they have like 4 different iterations of the Enterprise D, with the latest version using a mod to add more detailed blocks and still being worked on today, all the way back to the original.
