IDK why you’re being downvoted, you’re totally right. For this to be closer to a fair comparison, we’d need to know the averages for both countries over the same time period.
Let’s make the last 40 years our time window. China has dropped zero bombs in that period, making their average zero bombs dropped per day.
Now for the US, they’ve certainly dropped some bombs in the last 40 years. So that would make their average… Greater than zero bombs dropped per day… Oh…
That experience is highly dependent on the Linux distro you’re using. Steam comes preinstalled on gaming-centric distros like Nobara or Pop!_OS. More “general purpose” distros like Mint or Ubuntu might require adding an apt repository before you can install steam from their GUI package managers, but adding an apt repo can be easily accomplished with a GUI as well.
Basically, if there’s no guide for installing steam for a given distro, or the process of installing steam is more than a couple easy steps, that specific distro probably isn’t well suited to run steam.
