The Humble Indie Bundle is back, and it's even better than last time!

Last Spring's Humble Indie Bundle was the sale that took just about everyone by surprise. Not only did it let gamers pick up a number of great games for whatever price they wanted to pay, but it raised a total of $1.27 million (with almost $400,000 going to charity). Gamers have another opportunity to give back and get a little something-something for their donation, because the Humble Indie Bundle 2 just went on sale at 9 AM PST.

This time, the sale is starting off with another five games, and they're pretty big titles: Braid, Cortex Command, Machinarium, Osmos, and Revenge of the Titans (which is actually debuting with the sale). When you buy the Bundle, you can still choose to send your money to be split amongst the games' developers, as well as Child's Play and the Electronic Frontier Foundation. Purchasing all five of these games on their own would carry a pricetag of roughly $85.

The sale is still being organized by Wolfire Games, though the development studio doesn't have any of its titles in the Bundle this year. That said, generous gamers can still throw a little money Wolfire's way via the "Humble Tip" option.

As it turns out, the only reason a sequel to the original Humble Indie Bundle didn't happen sooner was simply because of time delays. "This is basically the fastest we could reasonably get an awesome bundle together," said Jeffrey Rosen of Wolfire when he talked to The Escapist. "We actually wanted to do it even sooner, but - like all software development - it got delayed."

Rosen has some high hopes for this new bundle, as well as the future for such projects:

"I think the humble bundle really has a lot of potential, and John [Graham, of the infamous Beard Ultimatum] and I actually recently started Humble Bundle, Inc. with the idea that this is just the beginning.

As for the potential of the Humble Indie Bundle #2, Rosen also believes that there's a possibility it could surpass the earnings of its predecessor. "I don't want to jinx it, but things are looking good," he said. "We have newer games, and people actually recognize the bundle now ... when we started no one knew what the Humble Bundle was."

Here's hoping the sale does even better than last time. These are great games and some great causes involved.
