Well if you exclude motion control, this gen wasn't really innovative. What are the big games of the generation ? Uncharted, Assassin's Creed, Gears of War, Red Dead Redemption ? Those are good games, but very similar to games we already had last gen. Only bigger and prettier.
I know what you're trying to say there, but I think you're WAY off base and not looking close enough.
Games of that type were attempted last generation, sure, and many of them were even successful. However, there's something to be said for the fidelity of the actual gameplay as opposed to visuals. There are so many smaller elements that all work together to create those games and allow them to feel as solid as they do that simply wouldn't be possibly last generation.
This generation we have sandbox games with more intricate controls, better collisions and animation, more refined AI, and more polished gameplay than many linear corridor games from last generation. Take something like inFamous or Assassin's Creed. The level of interaction with the world and fluidity of everything wasn't even common with linear games let alone sandbox titles from last generation.
Look at something like Uncharted or Max Payne 3 and consider the way everything works together. Animations flow smoothly, the collision with the world is top notch, enemies react beautifully to shot, etc. This kind of stuff isn't simply window dressing, rather, it goes a long way towards making a game FEEL really damn good. This kind of precision in a shooter simply was not possible last generation.
I feel as if a lot of people don't really give that stuff as much credit as it deserves. Those dynamic animations and physics all play a role in improving the experience itself and should not be discounted so easily.
