what's wrong with installing "manually?"

nothing.
you miss out on a bit of convenience though. cloud saves for example.

Biggest issue is that it is a hassle with larger games. You might have to download multiple installers and if your internet isn't consistent you might get an interrupted, requiring the use of another download manager. And then you have to manually check for updates and repeat the process with the update files.

That's how I did things originally and while I had Galaxy 2.0 (since it failed at downloading almost everything), but having this done automatically through Galaxy 1.2.* is much more convenient.

Obviously you also miss out on the other features of the launcher (ability to search library, cloud saves, achievements, etc.) but imagine that most people who are even considering using offline installers don't view such things as a dealbreaker.

I've switched to offline installers only since being force to use 2.0. 1.2 gave me a convenient way to see my library and have everything tagged. It's going to be more annoying, but I'm tried of having to wrestle with a client that I always close before starting a game anyway.

And you gained that number by reading ever post in there ?
If there is no counter attached you can't tell whether this was done by 1, 100 or 1000 users, so how should this be a good indicator at all ?

You yourself are responsible for around 20% of the posts in there and with "high rated" giving out no actual numbers, I wonder what this should this be an example for.

Mind telling me where I wrote that ? Or just show me one post where I denied that complaints exist

Again, never wrote that. But I am out of things to tell you except repeating what I already told you: people need to be bothered to a certain extent before they take the effort to complain. So thats why I think that there is a much bigger number of people (then that post here in the forum) that are very unhappy with G2 (bugs, forced upgrade, usability issues, missing features, etc.) but it works well enough for them not to take the effort. But getting off from my experience with humankind beeing rather lazy with positive responses my assessment is that there is a very, very much bigger group of people out there for which G2 just works as they expect it to: install>play>uninstall.
And till now you not even tried to bring any evidence (or at least tried to guess at) that the number of posts (including even the teeny tiny amount of non-complaints) represents a significant part of G2s user base.

But again, if thats your view of this whole thing, thats fine by me

I love the new Galaxy, so much that I completely uninstalled LaunchBox, which was my go to launcher for quite a while.

You never wrote this? ok then.

You do mind that small word "flooded" and the context and the point in time this was written ?

Edit: made the reference more clear and made the post lest aggresive

This thread was created Feburary 24 2020 so my comment has to be read in the context of that point in time - one of those "infamous" four sticky threads (still don't know what so special about them in the context of the point your trying to make) did not exist at that time and the one I created has all sorts of post, without the majority beeing critical about the state of G2, and those that are, also need to be seen in that context as G2 received several feature updates since then.
The part that you qouted also targets specifically the assesment of the op that G2 "is not even ready for beta", which it clearly was back then.

If you feel the urge to continue this nonsensical waste of tme - feel free to do so, I am out

If you actually paid attention to my post, the reason for mentioning the sticky threads was pretty obvious. It was to exclude them from the count of active non-sticky threads. They aren't the focus of any of what I was saying. I mentioned them specifically to exclude them from the rest of the count I was making. And that picture hasn't changed meaningfully by the inclusion of a new sticky thread, nor does the addition of one more sticky thread make any difference to my point.

And at present, Galaxy 2.0 is STILL barely ready for beta, and definitely far from being ready to be forced on users in its current state. So I don't see how that looks any better now than it did then.

The only one being nonsensical here is you. If you want that to stop, you can do so pretty easily.

Agreed. It takes about 40 seconds before the client even starts. Integration-Plugins crash left and right. Tagging or hiding games is not possible per platform (which begs the question why I should use Galaxy instead of different clients if I don't have the same functionality then). Demos will be stacked with the full games (so you cannot hide them either and game tracking/achievements for demos and full versions is always the same. Sorting py purchase date (which is a highly demanded feature) still is not possible. Whenever you download an offline installer via Galaxy 2.0 it creates a tmp folder as well and they don't even delete it after the download (a fix that probably takes a second to implement ... told them months ago - guess what, it still is not fixed). Community features like the activity feed here on the websites are rather incomplete. Many features aren't optional even though people demanded them to be again and again. Last but not least: looking at the sheer amount of tickets open in mantis is showing how many issues the client still has.

No, the client is far from finished and there's a reason it is called beta. With GOG mostly just focusing on the integration part instead of the basics and with the speed the updates roll in (I guess it is one update in 3 months or so? And I am friendly here) it will take a long time until this client will be really good. They probably forced the new client so that they won't have to support the old one anymore. This way they also get even more feedback (incluing complaints) .. but what's the point if they simply dont react to the feedback? I guess everybody still remembers the legendary "We listen to your feedback" thread? What happened? They listened and they ignored. GOG really needs to communicate more with the customer otherwise they will end up with a client that they adore but the customer hates.
