SLP2000: But there might be more, I don't know the case.
That's it. But you see, Interplay had to okay their releases with Bethesda and clearly Bethesda would not have okayed something with that name given that they were developing Fallout 3. The "Trilogy" was pretty much a case point that Interplay had not complied with Bethesda's requirements for publishing the old Fallout games.
As for Hasbro / Atari, Atari bought those games. Just like Bethesda bought the Fallout IP at around the same time. Just like Atari how would have to buy the gold box games before they could be sold again (until, as you say, 2017). Atari owns the rights to the infinity games. Hasbro owns the D&D license. Without a deal between them those games aren't going to be sold anymore.
Just like a lot of Star Trek games.
Just like the gold box games.
If Hasbro bought those games then you'd be seeing them listed as the publisher. Now I don't know exactly what the deal GOG did with Hasbro involved. It could have been reassurance. It could have been necessary for Hasbro to okay it. Either way, if Hasbro could allow other publishers to release D&D games then their legal spat with Atari would have been entirely unnecessary. The fact that they needed to fight to free themselves of Atari proves my point beyond doubt.
The bottom line is: none of what we're discussing makes the gold box games seem any more likely to make their way onto GOG. Either they're bought and released here or they're not and they won't be.
