It is no secret that the Humble Bundle charity service is extremely popular amongst gamers. If you did not already know, the Humble Bundle is a group of games that anyone can purchase for any cost. If a buyer spends more than the average payment, they are granted a set of bonus games and content. Then, the buyer can decide how to allocate the money the are spending. They can usually decide between multiple charities, the games' developers and the Humble Bundle organizers. The two most common charities included in the bundles are Child's Play and the Electronic Frontier Foundation.
The Humble Bundle service began its weekly bundles not too long ago. In the span of a week, the Humble Rougelike Bundle has already sold over 103,139 copies, with 9 hours remaining! If buyers spent more than a dollar, they can unlock all of the games in their bundle on Steam. Partnering with Steam to allow this promotion, in addition to offering games DRM-free (Digital Rights Manager) seems to have helped increase sales.
The games included in the Rougelike Bundle were: Paranautical Activity (Early Access Game), Dungeons of Dredmor Complete, Hack, Slash, Loot, The Binding of Isaac with "Wrath of the Lamb" DLC, Teleglitch: Die More Edition + Guns and Tunes DLC and Sword of the Stars: The Pit - Gold Edition. With games like these and charities benefiting from most purchases, it is no wonder that the Humble Rougelike Bundle has drawn more than $500,000 USD.
