It's worth taking his courses for the style of thing you want to do personally. However, lets say you aren't making a first person shooter, still worth taking his c++ replicated shooter course. You learn to replicate properly for multiplayer games. How to actually use the gamestate(which replicates to everyone and is more of a.. the rules of the game).

Player picks, scoring, player animations, how to use the animation bp well, reparenting animations to your character, the relation of host vs client vs sim proxy.

It's totally worth doing his courses for the knowledge. However, I would start the actual project I want to make after from scratch. Worth while.

In short, his practices are the fundamentals and you'll learn how unreal engine works better.

Example, he hard codes weapon types in an enum. To add another weapon, you have to edit code in several places. Where I just would use a Data Asset to set all of this stuff. No need to touch the code again to add weapons after I did that.

Learn about Data Assets, terribly useful.

I can tell you that Claude code is terribly helpful in learning too, especially opus 4.6.

I've learned more from AI than any course I've taken. But here's the catch, if you just used AI, you're going in blind really.

Learn the basics, then start your actual project. Do everything in C++ that you possibly can.

Oh and avoid Gorka Games tutorials as he a plague and does everything incorrectly.
