Arx Fatalis now has language parity with Steam.

I meant about the marketshare / increasing the consumer base so GOG has more leverage.

Ah yes, that is true. We can just continue to support GOG and recommend it to others. Both things we probably already are doing :)

But unfortunately it's still doesn't have regional pricing parity with Steam, just like many other oldies that Bethesda now owns (classic Doom, Fallout, Quake and Wolfenstein games).

GOG doesn't do anythig with this issue for many years, and Bethesda doesn't respond to such questions from mere mortals (customers).

Meanwhile, all recent Bethesda releases on GOG (including Prey) have no problems with regional pricing.

Darksiders III Digital Extras (DLC) -- The GOG version has the soundtrack in MP3 format only, whereas the Steam version has the soundtrack in MP3, FLAC, and WAV formats.

There are.
But result is gog remains small and other devs wont care about gog release as it is too small to matter.
Are there anybody who still uses WAV?

WAV is good for when you're doing work with the actual audio files, rather than just listening to them. For example, if you're going to use a program like Audacity or Ardour, it's easier to work with .wav files than to work with files that are already compressed, as if they're compressed, they need to be decompressed before use.

wav files are also useful for short audio clips that need to be played quickly and where compression isn't worth it, like sound effects in games. Playing a mp3 or flac file requires decompression, which takes some time and CPU resources; when you're trying to play a sound effect that's less than a second in duration, this does not make sense.

(You *can* convert between WAV and other formats, but that takes time and CPU resources, and there's no way to get back the data lost from a conversion to a lossy format like MP3 or OGG.)

Nice! Finally I can play again the version I first played years and years ago.

Yeah I get that but why would an average user need them? And these music are probably copyrighted anyway.
Imho it doesnt worth the extra download and space just to have wav. If someone needs it I bet it could be converted from FLAC easily or even from MP3 who cares if it differs from the original WAV so minisculely nobody can hear the difference.

Ah it's out? Yeah, I was aware of this. basically PvP even getting to platforms other than Windows/Steam was a maybe.
Will be added in the next round.

So they added the OST and kept their promise that they'll look into it? Great - I knew these were nice people. I'll have to write a "thank you" e-mail to my contact :)

So they did.

Dying Light got the extras (novella, 3D printer models, soundtrack, artbook and wallpapers).

According to a forum user Cat Quest 2 Is missing an important update for months now. Can anyone that owns the game confirm if that is true?
