How has gaming developed

If you mean like video games, then...

It's devoloped a LOT. First, it was just the SuperNintendo, or games where you could only move in a straight line, like Mario. But then, they got it so it was a birds-eye view o the game so you could move one space at a time, like the early Zelda games. Then they fgured out how to get the character to move around and how to make the graphics a bit better (along with the music). After a few similar game systems, you can now swing a white stick and have the TV knwo where your hand is moving 8D
Theres more to it, but that's the main
