Portal - Still Alive.
This is mine and Jonnes vote =)
It'll never happen... or will it...
It will...decision made~
Well, I do believe Chrono has spoken.
A cover of Still Alive (from either Portal or Mirror's Edge) can be represented by this equation:
MaSu + StillAlive = Win * Infinity
(This is how epic of an idea I think this is: I did more than lurk for once.)
