Brian Moriarty (creator of Loom) speaks! Besides explaining how Loom was originally meant to be a trilogy, he adds an insight on the reason its sequels never came out:

Contrary to popular belief, the LOOM sequels were not abandoned because LOOM didn't sell well. LOOM has sold more than half a million copies in various formats since it was published in 1990. The reason the sequels weren't made is because I decided I wanted to work on other things, and nobody else wanted to do them, either.

As a huge fan of Loom I'm not sure which saddens me more: the original theory that Loom did not sell well (aside from being an astoundingly good game, Loom had an Israeli version - in native Hebrew no less! - and sold extremely well here), or the fact that the trilogy was simply... neglected.

Another interesting bit of trivia: a Japenese re-arrangement of the soundtrack was made but never released. Moriarty sold one of the only existing copies on eBay last April. I contacted the buyer and hope to get the music available on the internet.

Last but not least, you know you've played way too much Loom when not only do you recognize the source of the following passage, but you can actually hear Cygna's voice in your head when you read it:

Destiny shall draw the Lightning
Down from Heaven; roll its Thunder
Far across the Sea, to where I
Wait upon the Shore of Wonder
On the Day the Sky is oepened,
And the Tree is split asunder.
