Imagine creating a game within say 3-6 hours with the above video. Clearly, you will not be able to do it within 2 hours since you'll have to rewind from time to time to keep up. The joy of self paced remote learning eh?
I've always believed that learning programming requires projects not aimlessly learning data structures or Big O run time bla bla. Sure you can learn stuff, but its like learning math at that point. You learned how to add and divide, but nothing of interest to apply them to.
Game development requires projects. It's project driven there is no other way to go about it. There is no learn this part and learn that part. You must learn how to stitch parts together to make a game or else you've learned nothing useful. Any course that has you learn about how to make a game must have a variety of game styles that you must create in order to get used to a game engine. This discounts the aspect of having artists to create assets or assets from a source (Epic gives away assets).
The Unreal Engine 5 is worth learning if you'd like to get into game development. Because of its live realistic renders, its gained usage in other parts of the entertainment industry, for instance film making. That vastly increases your opportunities to learn new things and apply them towards other projects.
To hone your skills, you must must must have small projects to try new features. How else can you advance and keep up? You only take more courses when you've lost enough knowledge that you can't do anything anymore, but that's unlikely if you've kept up with your own small projects.
The video up there is a good intro and if you like it look for more.
P.S. I got to say push against remote learning in schools is beyond inane. I'd argue those who effectively learn remotely are the most likely to succeed at what they do because they'll learn to ask themselves questions and experiment to answer the question. In person learning is only good for the first few grades after that transitioning to remote learning should be THE cost effective way to educate a population that continues to grow. Offering spaces for self paced remote learning away from home should be the norm since homes are typically not the most tranquil of places. Let's say it's a new space for growth of libraries.
