what's the big deal about Humble Bumble anyways?
They offer game bundles for a limited time and you can pay what you want.
You get more extra things, if you pay more and a part of the money goes to charity.
Some of the past bundles were really great (especially the one with Bastion).
You get games for a bargain, indie developers are able to promote their games and charity gets money.
It's a win-win-win situation.
