I've done a little research to discover a few issues.
The Movies publishing rights for the PC are still owned by Activision. They don't own the game itself nor the code or any ip rights. Microsoft owns all that. Its just that if it was to get a re-release, their palms will need to be greased. That said, Activision doesn't seem to be impossible to work with. With Microsoft probably not interested in The Movies at all, it will probably take a third party such as Night Dive Studios to get any movement on this.
Black & White 1 & 2 are still owned by EA. There were digital releases for both titles at the defunct shop.ea.com. They even have an updated page but with no purchase link for BW 2

With recent releases of Wing Commander 3 for free, I think there is a reasonable chance that we could get a release of that by politely contacting EA and Origin
Freelancer, Impossible Creatures, Starlancer appear to be all solid Microsoft titles. However that doesn't mean it can't be done. Tex Murphy was once 100% owned by Microsoft as well.
