Like the last humble bundles. Pay what you want. Define what you want to go to charity or to the developer. IMO, this is the best humble bundle so far. And if you meet the minimum you get more games. You can also activate these games on steam if they are available through steam. You can also download the games DRM free.
Standard games include..
Bit Trip Runner
Super Meat Boy
JamesTown
Shank
NightSky
Meet the minimum and get.. (the minimum shifts, it's usually under $6)
Cave Story+
Gratuitous Space battles
Crayon Physics Deluxe
Cogs
VVVVVV
HammerFight
And yet it moves.
