Similar in style to the crowd-favorite Humble Bundle, the Indie Gala is coming back for a second round. The collection includes three games that you can unlock for whatever price you'd like (minimum donations have been set at a dollar to ward off jerks and shady people). The three basic games are The Lost Souls, Battle Group, and Ichi. Pay more than $3.99 and you also get access to Xelorians, Call of Cthulhu: Wasted Land, and Little Stars For Little Wars 2.
You'll also get access to a couple of Desura-unlockable games and the PC game Tiny Plumbers which totally isn't Mario related at all.
