Has been done before as this is number 2, but that was before we got a PC section.

You get 5 games (Briad, Cortex, machinarium, Osmos and revenge of the Titans)
You pay from $/0.01 for them.
You feel good as its for charity and you are supporting inde games developers.
No DRM (You own what you buy)
