From what I understand the game engine got dropped in favor if focusing their energy on what Blender was meant to do - be a 3D art program. However, Godot 4 has native Blender support so you can load the .blend files directly. Thankfully since Blender is open source and the community is completely unhinged most of the time (in all the best ways mind you), there is a fork of Blender that is all about the game engine you can check it out here: https://upbge.org/

As far as the GameDev.tv Blender courses go however, Grant is an amazing instructor so I'm sure anyone who picks up his Blender courses will love it. He also has his own youtube channel with a ton of beginner friendly tutorials, specific guides, and general skill improvement challenges so definitely would be worth looking into if you are new to Blender and want some extra material to learn from :)

Good luck on learning blender mate ✨! Learning it defo opens up brand new opportunities for your future games (whether it's a custom prop, characters, artstyle, etc). Hoping to do the same with myself too (I wanna give VR GameDev a shot in the future so this is a great stepping stone!)
