(1) So, paying companies to offer us something, which we then still will have to pay for?
- How about: no?

(2) Man, I remember, when "Change.org" stood for attempts to raise awareness towards actual social issues and hopefully get decision makers to act on these issues.

I guess, that has changed, huh!?

(3) Yes. Sometimes there are license issues. Not always, mind you.
And while, of course (!), everyone likes making money, sometimes, people just don't like to hand over something, in a form, that has no restrictions (here: DRM) attached to it.

The people who own the rights, may see a DRM-free release as: "well, if we hand over our (easy to copy) digital product just so, then everyone can simply duplicate it for their friends and family...and where's our profit then?"

Apart from the above, and especially in case of very old games, another point may enter the equation: they simply don't recognize a high enough market interest, to promise a satisfactory amount of revenue.

A few posts further down someone mentioned "a threshold" that needs to be reached (the person proposed 500 people, willing to invest money, as that threshold) to make companies rethink their stance.

Look, even if we would be willing to shill out 'today's full prices for new releases' for these old games (I definitely wouldn't, btw), 500 x $50 to $70 is still "only" 25k to 35k.

Now, I put the only in " ", because 25k to 35k may be a lot for you and me, but these companies probably spend that (and more) on their legal departments already, before the first signature is put on a watertight contract with GOG.

Edit: typo

He would change the store name to Y and people would still think it stands for Good Old Games.

Didn't they tease something for GOG's upcoming 16th anniversary, something you'd want to stick around for?
Maybe they did manage to convince other rights holders of similarly older IP and respective games, that up to this point had been reluctant but when presented with the numbers of sold copies of Diablo, WarCraft 1&2, HoMM3, HoMM2, Blood Omen: LoK or the RE Trilogy finally caved?

Nothing extra really.

If they have been voted for with Community Wishlists, that is about the maximum we can do.

I'm sure GOG shows such wishlists to the game providers in question. Those providers may even keep tabs on them themselves.

Game providers would have to know their games are desired, so we wouldn't be telling them anything they did not already know or guessed at.

I guess the reasons are many-fold. They don't like GOG or don't like DRM-Free, too much work involved, too difficult due to the licensing situation, some other agenda, etc. Maybe there is loose plans afoot for a remake or sequel etc, and so they are holding off.

Normally the anniversary date passed already.

Depends.

Which anniversary are we talking about here?

The "GOG coming into existence" anniversary is over, that's right.

However: the "GOG is open to all now" anniversary is still coming up: October 23th.

It was October, 23th 2008, when GOG went from "closed EA beta for selected users" to "open beta with access for all".

What can we do? Buy more games. At full price.

Shouldn't we get the earlier Armored Core games before we get AC 3 and 4? And weren't they console only?
Same with Football Club.. But EA is notoriously hard to get to release games here.
