Sixth iteration of Indie bundle gets smallest return since second offering

The Humble Indie Bundle 6 closed today, selling over 300,000 to raise over $2 million for indie developers and charity.
This may be a lot by Kickstarter standards, but it's the lowest sales have been since Humble Bundle 3 kicked sales up to over $2.1 million.

Humble Bundle V was certainly a tough act to follow after it raised over $5.1 million from nearly 600,000 purchases at an average donation of $8.53.
Though some saw the previous collection of games - Bastion, Amnesia, Limbo, Sword&Sworcery, Braid, Super Meat Boy, Lone Survivor, and Psychonauts- as a bit of a departure from the usually humble offering, Humble Bundle 6 returned to the old pattern of mixing a few hits in amongst relative unknowns.
This strategy has made the Humble Bundle and indie packages like it a godsend for the developers lucky enough to get their games included in the mix.
