Is this worth it?

I recommend you first go through official tutorials from Epic, you’ll find them at the docs page and their youtube channel. Then I suggest you use the Wiki and study content examples and experiment on your own. By now, you have learned a great deal, and you can take another look at this and other paid courses again after that. The Udemy course do not teach advanced C++, which is fine, but the basics of C++ you learn in that course you can easily learn from free C++ tutorials, which there are PLENTY of, just google and youtube. It would be easier to give you recommendations like this if I knew anything about your experience though, do you know some programming from before?

The Udemy course, about 50 lessons seem to be dedicated to just installation and introduction of Visual Studio/XCode and very basic programming principles.

You are also paying on the promise of content. “The final course will be over 30 hours of content and 200+ lectures.”
Right now there are “only” 14 hours worth of content.

Personally, I’m not really fond of academic types that just spend a little time familiarizing themselves with a topic and now they are ready to teach you. I prefer to learn from actual game developers with a lot of experience. This Ben Tristem guy, calls himself a game developer, but all I’ve seen him do are tutorials on Udemy.

Quite a number of people who teach game development, who don’t actually do game dev.

It’s like these C++ gurus (like Scott Meyers) who’s never written an application of any size.
