Glad that you might find some games interesting! The comment chains on lemmy are not working too great for me either. In the web UI of programming.dev and the liftoff app your comment in my notifications is fully interactable and therefore I am able to vote or reply. But if I remember correctly, the web UI is fully broken and shows my reply instead of your comment in my notifications if I reply. The context stuff is also interesting. On the web UI the context is not complete and I have no idea how it chooses what it shows. In the liftoff app it shows the context but a lot more than what I personally would call "context" (the complete tree of the root comment that was replied to). AND I am sorry, I missed your notification. The notifications in the liftoff app are so subtle that I basically have to check manually if I have any. And I don't check because I don't expect any.
Addendum: for Guild Wars 2 I have a shitty "guide" if you need one: https://gist.github.com/Nithanim/443362f7b76d9a8d18abea2cb0daa00e
I would like to suggest my wooting keyboard. It is not quiet but i think their switches should qualify as linear. Not sure about the layout but I have the german layout so that might be a "yes"? I have the 100% variant. Sorry, i am not very deep into keyboards.
Their config tool is basically a website, so as long as you have a browser with webusb support on a system it works. Had some problems with the udev rules (most likely a "me" problem), so I used the desktop version instead.
Bonus you get is that the switches are an analog input. So you can change mode to analog and have like "slow walking" in games. Though, I have not tested that yet.
BUT it is hella expensive.
I also have cheap paddles (i think that that is the right word?) off amazon i use often. But the "support" is basically that the config is saved on the device so you config it once in wndows and that was it. I just bound it to random keys once and assign them in games. Would need to dig up what the paddles are called though.
