Most Webbrowser Support ftp.

None of the popular web browsers support FTP. Maybe some niche browsers still do, but certainly not “most”.

You specifically said “online servers for authentication”. That’s what I understood as just that - a server required to be able to play the game, not a server required to use an actual online feature of a game. Don’t get me wrong, I very much prefer when games allow multiplayer games without requiring a server run by the publisher. All that is very different from what the posts title is about, though.

By the way, there are still games on GOG that let you run local servers for multi player gaming.

online servers for authentication

I am not aware of any game on GOG that requires an online server for authentication. I’m not saying no such thing exists - I don’t own every single game on GOG, but that would go against the whole DRM free thing. Care to name a few games that do this? I don’t mean games that have an online mode that require a server, but games that just require authentication against an online server to be able to play the game.

They don’t have DRM. That’s not the same as owning the game.

That’s why I mentioned that you purchase a license. That has also always been true even if you “bought” a game as a physical copy in a store. A DRM-free game is still the closest thing you get to owning a game.

If you don’t back up the games or installers yourself, and GOG goes under, you lose access to your library the same as Epic or Steam going away.

I have heard this argument before, but I really don’t get it. Of course you could lose your files if you don’t download them. I’d say that’s so obvious it isn’t even worth mentioning. If you lose or destroy your physical copy of a game you also lose access to it. Pretty obvious.

Reminder that you do not own digital games

That is not universally true. On GOG for example you can download all your games, so things like this could not happen there. Sure, you still technically purchase a license and do not actually buy the games, but for all intents and purposes this is still the closest you get to actually owning the games.

also i am having trouble hunting down what cuesheets means in this context?

When you rip an audio CD you can either create one file for each track or you can rip the entire CD as one track and create a cue sheet file which is basically a text file describing where each track starts in that single audio file. This can be useful to have an exact copy of the CD without adding unintended gaps between tracks. It is primarily useful if you intend on recreating the actual audio CD at a later time from the ripped data. Most people don’t need this.

Can anyone explain to me if a headless chrome browser is dangerous the way a regular chrome browser is?

Almost. You want to make sure to keep it as up-to-date as you would a regular Chrome browser. It does almost everything a regular Chrome does, including running arbitrary scripts on websites.
