Just wanted to say that I just finished the Unity course and it was really good! I gave it 5 stars once I completed.
However, I did think there were some pretty fundamental things that the course did not cover. One of the biggest things is any form of save system. We went in to the basics of setting a value in player prefs but I do not think any Game Developer would be saving something like that to a clear text file. Also that is pretty simple, what about games that require you to save the entire state of the game.
Also on a smaller note, there was no mention of a pause or pause menu. I think I can look this up but was surprised is never came up in the course.
