There seem to be two. One with developer commentary, achievements and such (basically a later released better version) and.. well.. one without that stuff.

So, which one is available on gog?

I only played The Breakout for a few minutes last night but it looks like the achievements are there. So is the commentary, although I think it's in German only.

Thank you.
A bit sad that they didn't translate the commentary though. I know that pain although in this case I wouldn't need a translation. But, for example, if you unlock the voice cast interviews in a BlazBlue game, you don't get subtitles for the Japanese interviews either.. nor did they make some interviews with the English cast. Such things suck. :(

As far as I can tell, "The Breakout" is the latest version (1.2) of the so called "Sammler Edition" (Collector's Edition) that includes commentary and achievements.
"Harvey's New Eyes" on the other hand seems to be an updated version (1.3) of the original game. Unfortunately it does not seem to be the Special Edition that includes commentary and achievements.
Does GOG plan to release an updated version of "Harvey's New Eyes" at some point in the future since pictures 4 and 6 on GOG's Edna and Harvey site are from the Special Edition of "Harvey's New Eyes" (picture of game developer in the upper left indicating available commentary for active screen)? That would be really nice!

Please update Harvey's New Eyes to the special edition (developer commentary, achievements), Daedalic and gog.com. I'll wait for that before buying.

What do you mean by achievements? As far as I know, Harvey's New Eyes has achievements only on the Steam website, and The Breakout doesn't have them at all. Do you mean that the special editions have in-game achievements like Chains of Satinav? Does Harvey's New Eyes even have an English release of the special edition ANYWHERE?

By the way, in this version, the credits end with an out-of-place text saying "Special Edition". It's obviously a bug, as it even hides the text "Thanks for playing the Game!". Did anyone notice this?
You can see it in the end of this YouTube video:
For some reason adding a URL to the video hides my post... so just search "Harvey's New Eyes (Part 22 + End 1 - Contradict )"

And also in the attached screenshot.

I've watched German walkthrough videos on YouTube and the problem is not there. Odd.

Achievements in "The Breakout Special Edition" (included in the GOG package) are in-game achievements done especially for the special edition version (there is a menu with pictures and short descriptions of the achievements you can unlock).
"Harvey's New Eyes" in its special edition is available on Steam but without "The Breakout". GOG has the much better value with their package. And personally I think that they are doing a great job at providing us with additonal material, updates etc. So I still hope for the actual special edition of Harvey.

Are you sure it's the special edition? I mean, I know there are achievements for this game on Steam, but I'm almost sure they're not in-game - you can only see them in the Steam website...

I saw the pictures on gog, that the commentarys are available, but they are not for the 2. game?
Thats confusing. It's so old, and still not updated-.-

It seems that the second game, Harvey's New Eyes, has been updated to version 2.0, so does it now have the above-mentioned in-game achievements and German commentaries?
