@why @kaliranya some would argue that steam sales aren't as good as they were years ago even to now and could be seen as decline or valve being more greedy, but i wasn't on pc gaming around that time so i'm not sure.
i guess another reason is that the quality of video games weren't as good/fun as they were like 10 or 20 years ago. that also seems true but that's not really a fault of steam and more of vidya as a whole- but it can definitely be felt on steam.
