Yep, that checks out, added, thanks

Nah, I've not actually checked but I'm pretty sure that the works of Sir Arthur Conan Doyle are out of copyright and therefore in the public domain so you can do whatever you want with the Sherlock Holmes characters without paying anyone

Yes to Revenant, Ecoquest (put the 2 together into 'Ecoquest series') Cruise for a corpse (although I got U.S. Gold - Eidos - Square Enix rather than Interplay) and Prince of Qin series (Seal of Evil is the came-out-after prequel) added those

Psygnosis rights have, apparently ended up with Sony who are hoarding them, sadly

I'd already added Noctropolis myself but, like, really recent so I probably ninja'd you on that one :p

Even though Future Wars was developed by Delphine as part of the same series as Cruise for a Corpse, I'm getting 'Palace Interactive' as the publisher which hits a brick wall as far as I can tell - why did you think these 2 were Interplay? Maybe they had the American rights?

Thanks for these, especially Prince of Qin, that one looks pretty interesting, Mobygames has 'GMX' for the publisher but your post made me look again and I found that Strategy First are actively selling Seal of Evil on their website!

*edit* wait, found this:

Yeah, Interplay in America hmm....

OK I changed the entry to
'Delphine Cinematique series (Delphine - U.S. Gold - Eidos - Square Enix (EU) or Interplay (US))' to cover all 3 games and yes the 2nd one was a James Bond game but only in its Interplay incarnation, the US gold one was called 'Operation Stealth' featuring a generic spy with blond hair!

I own the box release of Future Wars, and it has Interplay on the cover. The Delphine games had a bunch of publishers and a couple of name changes, James Bond and the Stealth Affair was published by Interplay, the other publishers had to change the name and it became Operation Stealth (and the protagonist went from James Bond to John Glames, or something like that) and Future Wars had a different subtitle. Cruise for a Corpse kept the same name regardless of publisher, I think. Of that one I have the Kixx XL budget re-release though. So... I don't know, Delphine kept the rights then? Never heard of Palace Interactive. Maybe they were the Amiga publishers?

Wasn't sure Seal of Evil was also Strategy First. I got mine imported from Australia with apparently Auran as publisher. *shrug*

EDIT:

Gah, you're killing me with your ninja edits. =P

Only on the box cover, the in-game character still had black hair.

Oh I think Palace Interactive were part of Palace Studios, the British Indie film company who pretty much kept the British Film Industry alive single handed for a while with films like The Crying Game before blowing all their money on the massive flop 'Absolute Beginners' and going bust, They made the Cauldron and Barbarian games in the 8-bit days

LemonAmiga.com makes reference to a Palace Software. Maybe they're the same?

my comments on some of the games:

Grand Prix Legends: I didn't get the problem with this one.
Magic: The Gathering - Battlemage: If Magic: The Gathering fits under Hasbro, this should fit too?
Redline: I am talking about Redline, an Accolade game which I think later was bought by Activision. (Edit: Sorry, I think Accolade is owned by Atari. Therefore, this one doesn't fit.)
Shadow Watch: Red Storm Entertainment was later turned into Ubisoft Red Storm, so Ubisoft most probably owns the rights.

I would like to suggest that Sentinel Worlds: Future Magic be added to the list under "Electronic Arts"
Wikipedia (and my childhood memories of the box and game) indicate that it was published by EA (who are already releasing titles on GoG) so there shouldn't be any issue with it being released here.
Plus, its a really fun game to play for those who like sci-fi RPGs (its takes a lot of gameplay ideas from The Bards Tale type games)

There is also a game called Hard Nova that is supposedly a sequel to Sentinel Worlds in some form. Never played it but Wikipedia says its also an EA title.

Some of the rights are not owned by Sierra (as the publisher of Grand Prix Legends) but by the entities (teams, drivers, tracks etc) that are featured in Grand Prix Legends.

GP Legends - Yeah, after the Codemasters debacle of Colin McRae and Race Driver being removed I've decided to consider anything with real world cars as 'licensed' sure GOG has GRID but Codemasters are still actively selling that on Steam - I don't think anything with real-world cars has ever been revived from the vaults (and stayed) stuff like Screamer and 1nsane have made up cars in them, This is why I'm including Burnout but not Need for Speed also

Battlemage - Microprose's ended up at Atari (yeah, that' s where they went, I remember now) so it seems reasonable to assume that the Microprose Magic game rights have reverted to Hasbro like the Infinity Engine D&D game rights have, Battle mage was published by someone else (did I say Acclaim - Activision or something?) so there's no reason to think Hasbro has the rights to then in the same way they don't have the rights to the SSI Gold Box D&D games
Confusingly, when Atari got the rights to Microprose it was before they were called 'Infogrames', when they were called 'Hasbro Interactive' but the rights are being auctioned off, as I say so we can't just assume everything Microprose or Atari has gone back to Hasbro...

Redline - Yeah, Atari, again, sucks!

Shadow Watch - Interesting to know that Red Storm = Ubisoft if that name comes up again but I still say that I'm counting an adaptation of a Tom Clancy novel as 'licenced' (and randomly creating new IP and slapping Tom Clancy's name on it as not) sorry if that seem a bit arbitrary, it's a very fine line, as I say!

well explained, thanks

Activision: Wizard & Warriors
EA: The Neverhood
Hasbro: Majesty series
Square Enix: Flashback series
Ubisoft: Pool of Radiance: Ruins of Myth Drannor

Dark Sun series, Eye of the Beholder series: Couldn't figure out the right holder :)

All of these are D&D properties, so I'd say it's Hasbro.

If we knew for definite that Hasbro had them back I'd include them but as it seem up in the air I'll count them as licenced from Hasbro and not include them (TSR - Wizards of the Coast - Hasbro) is the tabletop D&D rights progression

I already have Flashback under Square and Fade to Black under EA, oddly
yeah as I said above, there's probably licensing issues between Ubisoft and Hasbro for the SSI D&D stuff so I'll not include it, I'll look at the rest later
Thanks

OK before anyone says, this newly signed Mastertronic doesn't seem to have access to the old Mastertronic (and I assume Virgin and Titus) back catalog, that, according to Wikipedia has gone to Sega (so at least we now know)

http://en.wikipedia.org/wiki/Mastertronic

Does anyone know if Mastertronic has got the rights to Spectrum Holobyte (and therefore maybe Microprose) from Atari or if they're dealing directly with the Bitmap Bros? I suspect the later...

Thanks
