Is Frontier hurting for cash that much? Because that's the only reason why I can see Atari reacquiring the game rights. I do recall them shuttering their Foundry publisher thing as they couldn't make that part of their business profitable (enough?).

*shrug* Either way, I owned that game here since the very first day it popped up on GOG, but I certainly wouldn't mind seeing it make its return.

I'm glad they've shut down Foundry, they took on a load of good indie games and slapped Denuvo on them

I'd forgotten I already had RC3 in my library

According to this RPS article Atari paid a cool $7 million for RCT3. Seems like an absurdly high price to pay for such an old game, especially since Atari retained all other rights to the RCT franchise already. Considering how long this game has been in circulation on the various platforms/stores they are not likely to make back that money either. *shrug*

Sabbas Eleftheriadis, the sole(?) developer behind old-school dungeon crawler/blobber The Darkness Below apparently intends to bring TDB to GoG once development is closer to the finish line:

From the comments section of the latest video update:

"NR: Don't forget about the future GOG release.
SE: I am not forgetting about it one bit. I will start working on it when I am done with the rest of the work for the other platform. Still, I am way off in terms of game content, so some balance is needed."
