Biggest innovation in gaming this generation?

[Avarice28]

For me the biggest innovation is that the story telling medium has become more descriptive; this probably lends itself to the overall graphical power difference this generation of consoles has over the previous. I feel like I am looking at real people with real emotions, not to mention the great strides the industry has taken with full motion capture, audio effects, physics, and graphical techniques such as HDR, bloom, AA, and sophisticated shaders. I still feel that motion control has its place in gameplay and also its limits. Online as others have pointed out is nothing new to pc gamers so the infrastructure that is in place is different, but the over all content is nothing new (DLC, patches, etc).
