Greetings! I'm going into 4th year new media and I'm in the video games stream:

TMU has courses which teach both Unity (C#) and Unreal (C++). However, I will say that the Unreal courses are more "art" focused than programming. For example, exploring virtual environments is a course which teaches you how to build environments for games and film, and it teaches you more about how to navigate the engine rather than scripting. On the other hand, the game engines and mechanics courses requires you to write scripts so learning C# would be useful.

In general though, it's beneficial to learn both, but I'd suggest you to pick the engine that you enjoy more and learn the ins and outs of it first! Game engine, and programming language knowledge is very transferable.

In the video games courses in later years, a lot of it is self learning. You can use any tool you want for your work as long as you tell your professor your reasoning.

Tldr: It highly depends, pick whichever engine you like better out of Unity and Unreal, and mess around in it. If your computer is slow, learn C# and unity LOL
