JKHSawyer: Chasm: The Rift (Published by GTI and WizardWorks, which was eaten up by GTI anyways, so owned by Atari?)
Possibly
the developers of the Carnivores series own the rights to Chasm.
JKHSawyer: Blood & Magic (AD&D license)
It'd be interesting to see whether Interplay would be willing to sell their older D&D games to Hasbro, like they did with their Infinity Engine ones.
JKHSawyer: Black Dahlia (Take-Two or Interplay?)
Interplay published the game on some territories, while Take-Two published it on others. I would be willing to bet that the game does belong to Take-Two.
JKHSawyer: Forsaken (Published by Acclaim, no idea, didn't Night Dive score a bunch of Acclaim's games?)
Night Dive acquired the Turok games and might have been responsible for bringing Shadow Man back (though the game isn't published by Night Dive here). For the rest, Throwback Entertainment has apparently acquired 150 games from Acclaim's catalog.
JKHSawyer: Metal Fatigue (Published by TalonSoft, who seems to have been bought by Take-Two?)
It was also published by Psygnosis on Europe, so it might belong to Sony. Or, it could even belong to the developers who were bought by MumboJumbo.
