If you're into independent games on Mac and PC you're probably well aware of initiatives such as the Humble Indie Bundle and Indie Royale Bundle - where you get to set the price for a collection of qualitative indie games. Indie Royale comes out quite frequently and next up is the New Year bundle that is available for pre-order now (minimum price of $3). The twist to the story is that the games have not been named yet, so you're pre-ordering in the dark.
"The titles to be offered will include a premium blend of FPS and RTS (Steam for PC and Mac), an innovative single-player puzzle game (Steam for PC and Mac, Desura for PC, DRM-free PC and Mac download), an award-winning 2D platformer (Steam for PC and Mac, plus an enhanced version for Desura PC, DRM-free PC and Mac download) and a world premiere on PC/Mac for an acclaimed arcade shooter with a twist (Desura for PC, DRM-free PC and Mac download).

If it sounds good to you then you should head over to Indie Royale's website straight away.
