I'm surprised this hasn't gotten more hype:
Moonring - free on Steam.
https://store.steampowered.com/app/2373630/Moonring/Well made - by one of the developers of "Fable" apparently, no micro-transactions I've seen so far, just straight up free.
The only (possible) downside is that the look is very intentionally retro. Looks CGA with maybe a bit of Apple ][. Maybe that's why - it might not be exciting to stream.
The controls and interface are more modern though.
It's pretty much a new Ultima game.
