Some even pay for premium channels to watch it.
In the UK football is so deeply engrained they talk of doing public holidays for when the England team finally wins a major international cup IIRC. The Olympics had/has some special subtext in international relations. So following sports has been deeply normalised in ways that probably polarises other similar practices (but for other interests) into seeming very fringe
For mechanistically intensive games it can be enjoying to watch masters play at a high level. Watching people win 1vs3 in Elden Ring or people do high level play in Monster Hunter or Devil May Cry is satisfying for someone who knows enough to appreciate the skill without having the time/desire in mastering frame specific inputs (I prefer directing that degree of focus to learning an instrument out of personal preference)
I initially discovered game streams because I find them perfect for falling asleep to lol
A good gaming video library, would look like a "go on your own adventure book"
But the interactive video thing never really took off.
I used to watch a lot of streams about another videogame (shooter). It is calming, no hard thinking, sometimes the streamer reads your comments which is the dopamine moment, also there is an ability to listen to some kool kid without a risk to be bullied. In my case it was a learning about how to play shooter games, what is FPV/TPV, where the danger is coming from typically, how to play while being on a low ground, or a high ground, how to use different gun parts. Sometimes donaters use to send payed challenges for the streamer like win the game having some handicap for which is always give some extra bits of entertainments because I know the streamer has a hard time.
Last but not least is the reason that my computer is a bit slow so connecting to the game takes a lot of time and there is a risk to be killed early which means at least 10 minutes of concentrated mind wasted, but seeing the streamer killed means I am in one click from another game on the culmination point.
What is not understandable by me is why Minecraft is interesting at all. Watching a proper shooter game is mostly the same as watching some military expert telling (for example) about how to clear a building, but playing blocks stopped being interested for me as soon as I have been introduced to some real-life activity like soldering some electronics - but there were no brainrot in my childhood.
Yes!!!
I've recommended to my adult friends to play minecraft for at least ~5-10 minutes before they die.
There is something amazing about being able to dig wherever, build whatever, etc... There is a sort of freedom that I never had with blocks.
I am not telling these people to kill the ender dragon, but rather, play.
Actually, before Minecraft, Notch worked on a game called Wurm Online, which was a tedious and buggy MMO but which allowed you and your friends to manipulate the sandbox world, dig holes, flatten the environment, build roads, etc. With teamwork, they could do some really interesting things. But like I said, it was pretty tedious and slow.
Watching other people play video games (or sports) isn't my thing personally, but to each their own.
Children watching minecraft videos instead of playing minecraft don't even have to get off the couch. They just have to reach for the controller and remote, or even just for their phones, and they can do the activity they've been watching someone else doing.
Playing with blocks is fun. Watching a stranger who can't see or hear you play with blocks seems far less fun, but kids spend hundreds of hours doing exactly that.
I can understand people watching other video games that have characters and a plot, and I can understand people watching sports which have teams/players and a contest with an uncertain outcome, but watching a stranger play with blocks where there is zero story and zero stakes seems insane.
There's no compelling narrative however, no drama, no danger/thrills, no ticking clock, no "will they or won't they", and no production value.
