Let’s be clear about this: there’s the EGA version of Loom, and then there are the imitation versions. Unfortunately, the initial and definitive release has been out of legal circulation for a lifetime; what you’ll find representing this classic on Steam, GOG and wherever else is the “VGA Talkie” version, which Brian Moriarty himself has gently called “an abomination” for its revisionism and myriad of compromises.
Limited Run’s Monkey Island Anthology from a few years back offers some hopeful precedent for the inclusion of archival builds, as the USB stick in that package came loaded with a bunch of legacy versions of the game (original .exe’s included, which is crucial in a world where DREAMM exists). The idea of the upcoming Loom box following that lead was hoped aloud for on the forums, leading local poster restoration pundit – and by now routine collaborator on these LucasArts Limited Run releases - Laserschwert to confirm that the EGA build will be included. Justice.
Honestly though, can’t they just put all these old SCUMM builds on an FTP server at this point? I mean, what are even talking about here. Cripes.
