@Ryona420 and
@Happy Camper captured my thoughts perfectly, but I have a few things to add
1. I coded some python scripts to cut out busy work, which speeds up development
2. I don't have to hold back content for block updates. I update as I go along essentially, so my stuff is rather bleeding edge in some regard, and everyone has a front row seat to the ugliness
3. I generally go light on descriptions unless it's for an event or I have something special in mind. Even then, my events are rarely as long as the old ones. I don't have a legion of slaves to write events for me, so I work within my means
4. I have a decent pc set up, so constantly loading and closing hoi4 while having vscode open is no issue. Just having a 5600x and 32gb of ram has sped dev time a lot. It also helps running with running test games. Sometimes when I am away, I'll leave an observer game running to see how the ai behaves.
I am convinced that TNO fans are kids who don't play games besides hoi4, and don't read books. Which is a shame, because there are countless books with better writing than TNO. If you cannot read something without flashing lights on a screen, there are also many video games that outshine TNO. It's been said a thousand times, but Hoi4 is not supposed to be a narrative game.
