Loom is easy to find, you can get it on GOG, is on reduced price several times a year. And then use SCUMMVM and you can even play it on your phone.
But does it include EGA graphics or only the remastered graphics like a lot of re-released old games do?
The one on GOG is the VGA version, for the EGA one you need to resort to other sources more on the spirit of Monkey Island :-) .
Using ScummVM on any existing platform. The game should be easily... found online.
You can buy from Steam for pretty cheap, and then customize by loading in a recent version of ScummVM. This also works in 64-bit only versions of MacOS as where the base title is otherwise incompatible.
Beyond the graphical changes, I also seem to recall that the script is somewhat different in the EGA version. I wouldn’t be surprised if there was a fix from the community for this, though.
