I'm following a game development study in The Netherlands. We started off by doing a few basic things with C#. More specific, our first assignment was to write a textadventure, which was a 'game' you can play in the command prompt console that displayed text and processed input that you provided to the program. This was done in a 'Console Application' in Visual Studio.
After that, we moved on to a few basic things with C# such as how to write and how NOT to write code. This did not take really long, and we quickly moved along to the Unity game engine. One of the reasons we do not use Unreal Engine, is because the learning curve is really steep. With Unity, we gradually learned more and more, and were able to handle more complex things a little better in the later stages.
The path we follow during our study works really well for me (like the global steps described above), it could be it works for you as well, but of course everyone is different.
Good luck! It can get pretty tough sometimes, but when you make something that works it will feel really cool :)
TL;DR
C# is a really nice language to work with. If you pair this with the Unity engine you can make pretty cool stuff if you can keep yourself focused while learning how to work with the engine and how to program using C#. Unreal Engine is also really nice, but has a really steep learning curve compared to Unity, and it uses C++ instead of C#.

Maybe this could help you learning C#, I have not used it myself though but the topics look pretty good to start with
