I am not exactly surprised by most of what was detailed here, as the recommended structure for working in game engines has always been pretty similar in most cases, but i am happy to see that some things that used to be extremely complex, have now been simplified with some amazing tools, with LoopTools being a great addition
Also, being that i am geared towards designing in Blender, then transfering my creations over to Unreal, or a similar game engine like Unity, then using that modifier to "triangulate" is an absolute godsend
I can see me coming back to study these videos, or even the Modifiers deep dive one a lot until i have each ingrained through experience
I am very impressed how far modeling has come over the last 20 years, even in the last few years, it has increased vastly
