As if the basic premise of Mojang's 60 hour Humble Bundle charity programming marathon weren't enough of an incentive for you to hand over as many of your hard earned dollars as you want, the Minecraft developer is now being joined by Oxeye Game Studio and Wolfire Games, who will be creating their own 60-hour indie experiences.

Wolfire's game will be based off the same crowdsourced premise as Mojang's, which is an RTS shoot 'em up steeped in an ancient Egypt/steampunk setting. Oxeye Games, on the other hand, will be combining the second-place and second-to-last-place options from the genre poll by constructing "a dungeon crawler beat 'em up set in a post-apocalyptic World War II."

All three teams are live streaming their progress at the official Humble Bundle site, and there's still about 20 hours left to go make your donation and claim your games before the event comes to a close.
