I trust your research and will suggest more (unless proven otherwise of course) :)

Activision: Grand Prix Legends, Lode Runner: The Legend Returns, The Movies
Atari: Elvira games, Prisoner of Ice
CDV Software: Sudden Strike (many games listed under CDV are already on GOG)
Crimson Cow: A Vampyre Story (not sure if Crimson Cow is the right holder but most games listed under them are on GOG)
EA: Anno 1503, Sid Meier's Gettysburg
Hasbro: Magic: The Gathering - Manalink, Magic: The Gathering - Battlemage (these might be microprose as well)
Microprose: Dark Earth, Railroad Tycoon
Ubisoft: Anno 1602, Army Men series, War Wind series

GP Legends has branded cars (Ferrari etc.) and is maybe FIA licensed too?
I'm sure the 'Elvira' character is a licensed brand too
I'll check out all the other later though, thanks!

Rebellion: Aliens Versus Predator Classic 2000

Good lists, just wanted to flag up some possible concerns with licensed sources.

Derived from novel by Philip K. Dick.

Based on a film, assuming you mean the game created by Psygnosis. I wasn't able to find one by Square Enix, unless they acquired the rights to the Psygnosis title somewhere along the line. Otherwise it probably rests in the Sony vault with the rest of the Psygnosis bounty.

Based on multiple films.

I would still like to see UBIK and The City of Lost Children get a re-release though.

Where does Microprose go, though? - some of it seem to be with Hasbro, some with Interplay and some with Take 2 via Firaxis!

City of Lost Children is based on a film
http://www.imdb.com/title/tt0112682/

I'll check through the rest though, thanks

Ok added 2 Sierra Lode runner games, The Movies, Anno series (under Ubisoft), Gettysburg and sequel under EA, army men and War Wind series under Ubisoft via SSI thanks for them!

I'm holding off on adding anything Atari while its in the process of being broken up and auctioned off, trying to keep an eye on what's going where though

CDV and Crimson cow - yes many games listed under them are here but published by all sorts of different people and I can't tell if the games you mentioned could be published by anyone signed here

Did you mean Manalink? it seems to be a third party, open source community mod for the old Microprose Magic game
Battlemage was actually published by Acclaim, Activision bought their name but not all of their assets and if anyone other than Hasbro owned a Magic game it would count as 'licensed' anyway

As I say, I think the majority of the Microprose stuff ended up with Take 2 via Friaxis, some stuff does turn up from other people from time to time though, which is nice, still can't work out how Interplay ended up with Subwar 2050!
Thanks for those!

How about SCi? Kingdom o' magic would be a fun addition.

OK added Street Legal Racing: Redline (plain Redline was something else by Accolade which confused me)
Wrote the line "Sierra Hi-Res Adventure Series (nos 2 and 4 or Apple ][ emulation for the lot) (Sierra - Activision)" for Wizard and Princess (some of those Hi Res Adventures actually came Apple ][ emulated on a Roberta Williams Anthology I've got!)
Added 'Strike series' under EA (Mobygames lists a few publisher over the years but calls it the 'EA Strike series')
Added Frankenstein
Added DREAMS to Reality and The Devil Inside
Added Volfed - Squeenix via Taito, that's a new one, didn't know they got Taito's back catalog!

Avoiding Atari, as I say
Black Moon Chronicles is 'based on a comic book by the same name' so licensed BUT they used the same engine for a game called Persian Wars, added that, it may be 1C Company rather than Anuman but they're both here so that's OK
UBIK is based on a Philip K Dick novel - licensed
Leaving Microprose alone as I say, but Risk II would be licensed from the board game anyway
I already had Evil Island under Nival rather than Nordic
I'm getting Telstar - Take 2 for Armed & Delirious rather than Sir-Tech but even if it was Jagged Alliance is Strategy First while Wizardry is Gamepot so they're looking a bit carved up anyway
You have Arcomage on your list under missing from the Might and Magic series so is part of that IP
I'm not seeing Shadow Watch under Ubisoft, is it because its based on a Tom Clancy novel? I'd call that licensed anyway (as opposed to HAWX which just has Tom Clancy's name tacked on for brand marketing, yes its a very fine line, sorry!)

Thanks!

I remembered that that Fool's Errand guy - Cliff Johnson is giving away his old CDi titles as freeware
http://www.thefoolsgold.com/downloads/CDI-games.htm
But then I'm really not sure that's properly legal, especially the Hanna Barbera one...
Licensed from films and that!
And the publisher is listed as Fox rather than Rebellion on Steam anyway!
Thanks though
If you're thinking of SCi because of Carmageddon, the rights have gone back to its devs - Stainless Games, I don't think SCi have been signed by GOG
Unless you were just saying that GOG should do that and not making a suggestion for the list?
Thanks

Added a bunch of stuff to 1C Company by going through my Groupees 1C bundle from a while ago

Guess its a suggestion for the list then, if Carmageddon was more of an exception then a rule. Also I would suggest Metalheart: Replicants Rampage for your 1C Company part of the list.

Really? Why 1C? It's looking like DreamCatcher - Nordic to me
Still Nordic's all good, added it to their part of the list
Thanks

I think EA should have the rights for The Lost Files of Sherlock Holmes series with The Case of the Serrated Scalpel and The Case of the Rose Tattoo.
