LithTech the engine isn't the problem. We have LithTech games here already (Blood 2 just to name one.)

As for NOLF, the reasons as to why thats tough is down to several different companies owning parts of it and not having an idea of where they are.

Since I cannot be sure that this would be released on GOG Day 1 of a re-release (if it's even going to happen), I felt it best to post this here.

Monolith Productions has posted some recent information for No One Lives Forever. They are giving away copies of the GOTY for the 18th anniversary during a stream on Friday, but they also updated their Facebook cover photo to No One Lives Forever.

If this came here in the near future, that would be a lot of wishes granted!

Sunset Overdrive the previously Xbox One exclusive game is coming to PC in a couple of days. A listing for the game just went up on Amazon, and it seems like the publisher is THQ Nordic. At least according to Amazon. Maybe there's a small chance that it could come here?

Edit: Of course they could just be the publishers for the physical PC version and not having anything to do with the digital version. Won't know for sure until release day i guess. Microsoft Studios is also listed on the cover art along with THQ Nordic.

Edit 2: Although there are a few previously Xbox One exclusive games that are published on PC by THQ Nordic only for the PHYSICAL version so this is probably just going to be for the physical version with a Steam key or something :/.

Edit 3: Digital Steam codes for Quantum Break sold on Amazon also list THQ Nordic as the publisher, but on Steam Microsoft is listed as the publisher. Weird.

WayForward Games currently has no plans, but will take into consideration a GOG release of the Mighty Switch Force games:

Looks interesting. Voted the GOG wishlists

WayForward deserves so much more recognition than it gets. I love their games for their amazing sprite work. They have very talented artists, and I'd love to get the Mighty Switch Force series DRM-Free. Until then, voted. Thank you for the news, SCPM! +1

Konami has recently registered trademark of Metal Gear and Metal Gear Solid in Europe

The devs behind Mage's Initiation - a Quest for Glory-like - have contacted GOG about selling their game here.

They're still waiting for GOG's answer.

Meanhwile, here's the Wishlist Entry

From a quote from PC Gamer, more Epic Games classics may be coming to GOG:
"We’ve recently worked with GOG on making classic Epic Games titles available and we’re planning to bring more of them to the store in their original glory."
It's not clear if by 'the store' they mean GOG or their own storefront or both.
https://www.pcgamer.com/unreal-tournament-is-not-being-actively-developed/

Most likely both.

Interesting, but other than Bulletstorm, Shadow Complex and Unreal 3. I don't recognize any other titles.

Unless they also mean the Infinity Blade Trilogy, which would be amazing news, if they ever decide to get away from the Apple store. Because, I'll never buy an Apple device just for Infinity Blade, and there doesn't seem to be any work done on an emulator.

EDIT: ...or Gears of War, if they ever decide to get away form the Microsoft Store.

Good to know that, despite opening a new store, GOG and EPIC are collaborating instead of going the "rival" way.

Better for them, GOG has some name power to it so does EPIC, plus they get seen as the good guys by siding with a drm free store, Hopefully
They also published a fair few games as well, like Solar Winds and a few other, they may retain the IP rights to those.

As brought up by PainOfSalvation in another thread:
Someone tweeted to Bethesda asking to release Skyrim on GOG and GOG official account retweeted it. Could this be the a hint?

Bethesda's Twitter account didn't reply. :(
