Some sweet upcoming new game concepts

I just came across a few videos of experimental game concepts coming to market (hopefully). 

First, The Unfinished Swan. I really like how the game gives me a sense of wandering around in the dark, but with pure white.

Achron, which absolutely blew me away. I have a soft spot for time travel and alternate time lines. A RTS (real time strategy) game that utilizes time travel to alter time lines sounds amazing.

 

I also have a soft spot for platformers, such as LittleBigPlanet and of course Mario.  In this game, you play a shadow figure and must manipulate light sources and objects in a 3d world to modify the shadows on the wall that you navigate to reach a goal.
