The gameplay, control and graphical leaps from Snes/Sega to PS1/N64 to PS2/Xbox were huge. Then the jump from PS2/Xbox to PS3/Xbox360 was not quite as huge. And it seems more and more, that games are the same as they were 4 years ago. There appear to be not very many improvements made, just sequels to previous games that look and play almost the same.
I was playing a few games on my iPhone the other day and the games did not look all that different from console games. The controls were slightly more clunky but otherwise, the differences were minuscule. The Wii U doesn't really look any better than the current generation. I also am really starting to doubt that the next-gen Playstation and Xbox will be that much better either. I'm starting to doubt if developers still have what it takes to wow us with new games.
-Have innovation and technical advancements finally slowed to the point where new games are barely any better than older ones?
