I have just started learning Python and decided to get extra practice and followed an youtube tutorial on how to create an adventure text-based game. Because the video was old, I made a few changes for Python 3.8 and added a few extra options for better navigation.

The current issue I’m running is NameError: name 'PlayerIG' is not defined. In the tutorial, the programmer made that variable global.
That didn’t work, so I passed as a parameter and it was working fine until a few other errors started to occur: EAttack was getting the same error (NameError: name not defined), but I made it global and that seemed to work until it didn’t.
I tried to pass PlayerIG into all functions that used it, but that didn’t solve the problem either.
PlayerIG is essential for the fighting system, please help me understand why it is not being recognized anymore.

Another issue is that in @property, the variable attack is not updating self.base_attack inside the Player class why is that happening if I used return?
I have shared all the code bellow.
This is the tutorial I was following //
