Creation Engine is static. Others, you are right, change.

Points out it does change.

That's like how Microsoft made Edge browser by forking IE11 and it's suppose to be better.

It is... By a lot, ask any web developer. Even before they switched to using Blink under the hood it was a significantly better browser. Now it's literally a reskinned Chrome. Meanwhile IE11 is a complete mess that requires a ton of hacks to get it to do what you want.

In both cases IE -> Edge and Edge -> Chrome Microsoft changed the literal browser engine. ... This just kinda makes my point even more so, the general public has no idea what constitutes an "engine change" and can't judge whether that will yield the results they want.

Oh my. Source 1 had that when Half-Life2 was released. Advancement.

You've seen how low poly Half-Life 2 is right...? Destiny 2 only allows certain areas to have the flashlight on because if they don't plan for it the flash lights can tank their frame rates (seriously) -- but hey "Left 4 Dead 2 had a flashlight in source engine!" /s.

I can almost guarantee Half-Life two also didn't have "Global illumination", maybe real time lighting for the flashlight, but Global Illumination is a much bigger thing.

This is Half-Life 2 with global illumination: https://youtu.be/WWYpKRETv8k?si=9eTDmx10m3l9nwdR

Here's an old forum from 2005 talking about how "real global illumination isn't yet possible" https://gamedev.net/forums/topic/348797-half-life-2-global-illumination/3282572/
