Well, wouldn't say it's been that long...
And I'm still not looking for new releases, so unless they show up here or are mentioned on the forums, I probably wouldn't know unless they're big enough to be in the general news, and it's been a very, very long time since I cared about such a title.
So the main list is basically the same one I posted then:
- Drakensang: The River of Time + Phileasson's Secret
- Dark Messiah of Might and Magic
- Tom Clancy's Splinter Cell: Pandora Tomorrow / Chaos Theory / Blacklist
But let's add
- Fable: The Lost Chapters
Since it was mentioned here and that reminded me that I was interested way back in the day.
And this also makes it easier to get to ten, since when I filled in the list at that previous thread I had a hard time with the last "slot". So now I'll leave SimTower out and complete the ten with
- Kohan 2
- Dyna Blaster (Bomberman)
- Lemmings (maybe make it a bundle with all)
- Stunts

But I'd still really want some freeware titles to be here, for exposure, ease of access and preservation:
- The Spirit Engine 2 (first one too if we're at it, but 2 is the relevant one)
- Elite Plus
- Heroine's Quest: Herald of Ragnarok
- Supaplex
- Castle of the Winds
- Traffic Department 2192
- UnReal World
- The Lost Vikings

Seeing someone mention a title containing the word "Lost", perhaps it's time for a release of Leisue Suit Larry 4: The Missing Floppies. (I wouldn't actually buy it myself, but I suspect some people would be interested.)

We could also look at other 4th games in series that might be interesting to have:
* Wizardry 4: The Return of Werdna (the most serious list entry, though not the most serious game; while we're at it, how about the rest of Wizardry 1-5?)
* Ultima 4: Quest of the Avatar (except that GOG already has this game twice; so in that case, maybe I'll specifically put the NES version on the list, as it's sufficiently different from the DOS version to warrant a separate release)
* Might & Magic 4: Clouds of Xeen (you can play this as part of World of Xeen in the Might & Magic 6-pack, but perhaps the option to install Clouds alone would be nice, to play that game as it was originally released, before MM5 came out; note that MM5 alone can be easily played by renaming or deleting a certain file from the installed floppy disk version, but that won't work for MM4 alone)

Actually I'd enjoy trying out Molyneux's The Movies.

Oh, yes! A great game. Hopefully with its expansion: The Movies: Stunts & Effects.

Civilization
Civilization 2

(I don't understand why those two games are not on GOG)

Also:

Warcraft 3

AoE 1 and AoE 2 (probably not happening)

Lemmings, Lemmings 2 (like Civ, they should be here)

Dune (the old adventure game)

The Lost Vikings

The Settlers (so I could own the whole series here)

Some racing games like the Need For Speed series, or Driver.

It was very hard getting the list down to 10. Some games appearing on GOG would light up my day shortly followed by me instantly buying them with a big grin on my face. But even that list is longer than 10 games.

It was hard deciding which to exclude, but this what I have so far (in rough priority order):
1. Myth trilogy (The Total Codex, including The Fallen Lords, Soulblighter, Chimera, Worlds, The Wolf Age, and the extra maps, plugins, and content bundled with The Total Codex release)
2. Black & White series
3. Command & Conquer series
4. Fable series
5. Vietcong 1 & 2
6. You Don't Know Jack Classic Pack
7. Halo series
8. GTA series
9. Max Payne series
10. Marathon trilogy

Damn, forgot about my list. :P
Since 6 entries of my list released here in the last couple months I'll add a couple new wishes...well, one entry for now.

Yakuza 8

Watched the story trailer yesterday, it's going to be an amazing game and I'll probably get a.PS5 for it. :)

Myth The Fallen Lords/Myth2/3
Sid Meier Gettysburg/spinoffs
Sid Meier Civilization 1/2
Discworld trilogy
EA Jane's series of simulators
Microsoft Flight Simulator series
Panzer General/Allied General
Dungeon Master
......

I can think about many more. But If we think about the real/most important classics left are less than those already available
