Perhaps "big" is not the right term. Perhaps "historical" is better.

EDIT: No.

Alright, I won't try any more guesses. Way to up the tension. ;)

Not just big, but historical. Tell me, are you trying to replace Judas as the forum's teaser?

He's doing a hell of a job. :)

That's weird. Has RWS stated why it's not here?

Actually, i dunno. There is linux version on, say, Desura (and Steam OFC). Even more, if you write a letter to them with proof of purchase (GOG receipt is fine too) they will provide you linux build too. Why they cant\dont want to do that here, on GOG, officially - i dont know. I already noticed that all new releases on GOG provide linux port if it exists (except Bastion), but linux-ready games sold on GOG before Linux support was announced is getting its ports slowly - maybe its not high priority or developers lazy.

wow. such hype.

It's known that GOG wants to launch a German version of the page. For the French one, they offered Little Big Adventure for free. So maybe again a free game.

But keep also in mind that some games aren't allowed to be be advertised or sold to minors in Germany, e.g.

Edit: Added more games from another list.

Good thing then that GOG is available only to individuals who are of legal age to form a binding contract and legally permitted to use the Service. Or does noone ever read the ToS?

It doesn't matter, German officials are quite rabid when it comes to video game and movie censoring which makes the companies self censoring extreme, because nobody wants his game to be forbidden completely.
Even titles that are only sold to matures (a18) are heavily censored here, because "minors could get an (illegal) hold of them".

That's why we fear the dreaded censored versions here now.
Austria sometimes gets uncensored versions with German language and I really hope, that we will get those.

I am not a lawyer, but these publications on the index can only be sold to people who have verified their age and the Wikipedia claims that they can only be sold if the customer asks for them.

Exactly and that makes them non-existent, because the last time I knew a local PC shop that had those somewhere in the back or under the counter was about 15 years ago and I wasn't even 18 yet at this point.
If your livelihood depends on selling stuff, you go the safe route and that includes the publishers as well as the sellers.

Supreme Ruler 2020 doesn't qualify as either big or historical.

Indeed...
