If (and its a big if) it's Ultima they may wait before announcing it to the abandonware sites. Otherwise someone would have checked by now and popped into here to say "He guys its Ultima <link>"

There we go. Someone finally has hacked GOG servers and got announcement secret.
Ask and it will be given to you. :D

Just to push back a little against what seems to be the overall consensus at this point, I think the whole "it's the publisher, stupid" approach to the hints could be a mistake. Sure, if GOG gets developer X or game Y that naturally means that publisher Z is involved in some form or another, but (just to restate the obvious) it still comes down to exactly what games are included in the deal, and it may not be even close to the entirety of the potential retro catalogue of a single larger publisher. And while GOG could possibly add more games from the same publisher later on, there's no guarantee that they will be able to.
Thus, as far as speculation goes I think we get a whole lot more (relatively speaking) out of continuing to ponder the significance of the hints and their exact wording as it relates to specific game titles, rather than trying to infer some kind of seemingly logical but ultimately even more speculative link from game X to developer Y to publisher Z.

Absolutely but you were already a fan. The object of the movie was to make it watchable for people who had never heard of H2G2 before and in that respect based on box office and DVD sales it succeeded.

It's Pinball Construction Set from EA!!
Bard's Tale Trilogy!!
Ultimate Wizard!!
And... oh yes... Ultima

well, they could have pulled it several months ago to seem less inconspicuous.

I tend not to judge the movie by the original idea, be it a radio show, or a book.
Really. I didn't go berserk on LOTR either. ;)
Maybe it was a commercial success, but You know, so was Modern Warfare.. ;P
Bard's Tale.. Recently there was some sort of a remake of that game... made by..inXile Entertainment... X...
But I wouldn't go far with that assumption .:)

As someone who contributes to Abandonia, basically what happens is if one of our members notices something is available for sale, one of our main members (that is, those with the relevant access!) removes the download links. If anyone then asks why the download is no longer there, we point them to the place where you can buy it.

Abandonware sites may not pull down games if they are not available for sale yet. They are already skirting legality as it is. Unless they receive a cease and desist order from EA they are unlikely to hurry.

Doesn't Activision own the old Infocom rights?
However, I think the Zork trilogy is free already - I know for sure Zork I is, as well as Zork:The Undiscovered Underground.

How long until another hint comes up?

I think so. Sierra had them last that I am aware.
Interesting. Just checked that abandonware site with dogs in the name and only Ultima IV is still there...

Keep in mind that Activision didn't retain all of the Sierra rights. A lot of them were scattered all over the landscape.

Two per day, maybe?

surely tomorrow...
