Pong source code is available in many languages. You could have also made it in a second if you copied someone else’s work.
Now seriously: I make games for myself for 8 years now. It’s really really easy if you don’t have to please someone else. They are fun too (for my use case: 1 or 2 thumb controlled bullet hell games for long train rides)
However actual video games are hard to make. Can you make music/sound effects? Otherwise you have to pay for it. Can you make sprites/3D models? Otherwise you have to pay for it. There is balance (data science or you gotta pay for it), there is accessibility (you don’t wanna trigger someone’s epilepsy / can they play your game if they are missing a thumb?) Do you want a story (pls don’t), can you write it(pls pay for it if I have to suffer through a cutscene)?
if you believe sum of all the costs would be smaller than the earnings, go for it. Otherwise it’s a very fun hobby like painting or playing the guitar.
I like this video if you have 52/(youtube speed factor you can handle) minutes:

That’s literally true though? If it’s hard to see, take it to the extreme: If you were the only person in a place, you’d be the most important one by default?
They wouldn’t do a good job, but they’d have the job since, you know, there is less competition.
I did work and travel in USA, and they were paying us peanuts due to some law shenanigans (they had to pay overtime for Americans, not us.) Wouldn’t they have to hire a native instead of me if I wasn’t allowed to work there?
