Phaser still requires a ton of boilerplate code compared to the example games here.
Both Godot and Unity are very similar to each other and aren't great for say.. hacking together a quick js prototype and sharing it with your friends on the web (or with a lil' device).
I've been really impressed with how well people can build out really engaging games with simple graphics but interesting game mechanics. The community already has pushed it beyond what we originally expected when designing the engine.
For all the faults with Flash (security primarily) it gave so many people an easy way into games development.
We’re missing this today.
Just getting the environment setup for a lot of game engines today is beyond today’s teenagers (and to be fair, me - both in terms of required knowledge and attention span), whereas 40 years ago, you just turned your computer on and boom - a flashing cursor. You had to type things to even load games.
