Hi, guys!
Never posted here, just a simple (or not) question.
Which games will appear on GOG and which won't?
For example I see Heroes of Might and Magic and Age of Wonders, but no Age of Empires.
I see Warcraft, but no Dune.
I see Unreal, Quake, but no Half-life.
There's Wizardry, but no Eye of the Beholder.
How exactly do you choose games?
Another one...
How to filter by publishing year? Many people play good OLD games they already KNOW and LOVE, so for example I want to filter out anything post 2003 or so. How do I do it?

Is there any topic for reports about grammar errors on GOG site? We have one in Russian forum, but I'd like to report an error in English description of one GOG product.

For questions concerning GOG's website I usually contact them through Support
https://support.gog.com/hc/en-us/requests/new?form=account&product=gog

Then I include a screen-capture of the problem (a broken picture, download not working, etc) with the request and send the ticket. Always worked.

I don't think it's very productive idea to bother GOG support with reports about site's grammar.

Often it has to do with publishing rights. I think GOG is always trying to find classic games to put up for sale, there is also a Community Wishlist where you can request and vote on games you want them to add, but if a publisher has gone out of businesses and the rights to the game is now owned by some random bank or company it can be hard to work out a deal on who gets how much money, and if the rights are split between many different people it gets even harder.
Plus, games like Half-life, Diablo 2, Warcraft 3, and others, are often owned and sold by competing online game stores.
Valve owns Steam and want you to buy it from them so you start using the steam store.

P.S. Eye of the Beholder is on GOG but sold under the name Forgotten Realms: The Archives - Collection One
