Look no one can debate the facts. This bundle is making more money than previous bundles and will likely end up dwarfing the previous totals. More money for charities is better than less money for charities. Well done HB.
My issue, and reason for not purchasing this installment is that it feels sordid. I use Linux, Windows and Android and appreciated past bundles because they catered for everyone. I was very happy to support a group that did not care which operating system I wanted to use. I liked reccommending the bundle to friends, perhaps gifting them a copy of a game they'd missed. So I always paid a few quid more than the average as a result.
This bundle seems to have actively targeted one group in order to maximise how much money is made. The group that in all previous multi-platform bundles has paid the least per person (I mean look at the current average - less than $1 per game! - how can anyone pretend the average backer is "charitable"?). The group which always paid the most per person has been excluded. As someone who has tried bundle games on both Linux and Windows, I can say that this group not only gave more, but did so for games that were often riddled with bugs. But I digress.
This bundle is not in the spirit of previous bundles. It does not promote fairness and generosity. It is merely milking a cash cow. There are plenty of other charitable groups to support while the Humble Bundle gets a grip.
