Remember Space Invaders?

Stumbled upon this Q&A from USA Today with the creator of the original Space Invaders video game. I found it interesting that despite all the new technology available he finds game developers at the moment are going through a tough time due to the over saturation of games available as most video game themes have already been covered in the past.
He also states that the focus on unique concepts has waned with the evolution of technology, which I have to agree with. I remember when I was younger gaining much more enjoyment out of simple Atari games than I do now with the majority of games I play. In fact I tend to only ever play sports themed games now as the novelty has long worn off with shoot em up games.
