Humble Indie Bundle 4 is the most appealing one yet. Bundle 4 added five earlier games (and their soundtracks) this week and has now earned more than $2 million.
It's becoming less and less surprising to report these bundles are earning millions of dollars. Back in October, the Humble Frozen Synapse Bundle earned $1 million, and Humble Indie Bundle 3 surpassed $2 million in the final hours of its existence. The quality of the games being offered is a big draw, but it's clear that the bundle creators haven't lost sight of their inclusive approach to customers.
