I know there's no chance of it, but still hoping for older Blizzard games...

Alright, done.

Also, good list, even though half of them are incredibly unlikely - I'd love to see I Have No Mouth, Flashback and Neverhood. Also, it would be good to have Lemmings here - one of my all-time favourite games.

I Have No Mouth and I Must Scream is still being sold (CD copy) through Harlan Ellison's site:

So I don't know if he's the one who could let GOG sell the game. He should be, as he is listed as president of Kilimanjaro Corporation according to this site:
http://www.corporationwiki.com/California/Sherman-Oaks/the-kilimanjaro-corporation/40291474.aspx
which is listed as one of the copyright claimants to the game (hoping this link works)

I remember the first time I played the game and heard AM's voice I thought that must be the author of the story because no one else would portray AM like that.

New release : Return to Mysterious Island 2: Mina's Fate

the only game i want is vampire the masqeurade bloodlines p.s terrible at spelling sorry :(

You do know it's on DotEmu, right? Allergic or something? There's no DRM, and it has German and French if that matters to you at all. If you prefer waiting, though, that's your call.

Looks like it's Guilty Gear Isuka and Tomb Raider Angel of Darkness. With all the Tomb Raider games coming out on GOG, I really wish Square-Enix would tap into some of their other older games a bit more. :/

Two very "interesting" releases. Nothing for me, though...

It's on Steam; it's also DRM-free if you're concerned about that (you can run the game via Dosbox without having to run Steam)

Thank you! But I don't like Steam and I'm not going to open an account just to get this one game. I'm sure we will see it here in the future and I can wait (my backlog is long enough to keep me occupied till then).

We're getting Defender's Quest today.

It would be awesome if all those games came out on the same day.
