With holiday shopping (hopefully) under your belt and finished, you probably have five or so bucks left to splurge on yourself. You may want to consider the Indie Royale "Xmas Bundle 2.0," which packages seven games with which to distract yourself during family gatherings.
The bundle includes Colour Blind, Offspring Fling, Serious Sam: Double D and The Random Encounter, Puzzle Bots, and Little Kingdom. You'll also get a new indie title, Namiko, from Offspring Fling creator Kyle Pulver. Paying more than $8 will get you the album Rhythm'n'Bits by Yoann Turpin. The current minimum as of the time of writing is just under $5.
