Two game design links
First is an essay from DanC about the frontiers that are being explored in game design, there is where the innovations are created.
Mobile and Social games are just the tip of the iceberg of the evolutionary explosion that is pushing games into every crevice of society. Look around! The grand spirit of exploration and innovation is once again thriving like almost no other time in gaming history.

Second, from a comment on that essay, here is an interesting article on the usage of videogame using a physical feedback system to help problematic children learn how to control anger:
The pilot study at Children’s Hospital Boston tests an intervention that features a video game based on the 1980s arcade favorite Space Invaders. Players shoot down space aliens, but with an important modification: they wear a monitor on one pinkie that tracks heart rate as they play. If that indicator rises above resting levels—signaling that they’re overexcited—players lose the ability to shoot.
