Joel writes, "Humble Bundle is currently offering a massive amount of game development tools for a very tiny price. Several game engines, art tools, asset packs to help make your games, and more are all in the pack for $10-12."
"Plus, proceeds also support several charities: Child's Play, Extra Life, and IndieCade. This bundle is up for the next 11 days."
