I don't mind donating to charity, and have purchused pretty much every Humble Bundle so far, but I have to admit this is pushing it.
Rather than indie developers donating their games to collect money for charity, this seems a lot like someone developing a game trying to make money off of it before it's even done, it's not a bundle, it's one unfinished game. Even if most of the money goes to the charities even if you figure it makes like 25 cents off each sale that's a lot of cash given that he's got like 38000 purchuses already and is apparently in this one alone.
Sorry if this offends, but I call it as I see it, and really this makes me think less of them. This one doesn't seem to be about charity.
That said, since this works, maybe I should start a similar institution. I will offer to write pornographic fiction here on Da Internet, in exchange for money. If people send me money I'll give half of what I make for charity, and for every $10,000 I'll actually write something.... With 38,000 purchuses/donations of a game this guy might some day actually finish making, there must be someone out there willing to donate to "Theru's Online Porno For Charity" foundation.....
On a more serious note, I'm also wondering if this is for real, the guys at HumbleIndieBundle seem to have it pretty well together. Since this just went up today, I'm wondering if maybe they got hacked or something? I mean this does sound like exactly the opposite kind of thing that they are supposed to be all about.
