Depressed by its bleak perspective, alone and freezing in the digital marketplace, Don't Starve survives solely on mystery and cheek. The first self-released offering from developer Klei Entertainment – best known for attractive consoles side-scrollers like Shank and Mark of the Ninja – Don't Starve drops the player into an unforgiving boot camp in wilderness readiness.

Everything about Lego Star Wars: The Yoda Chronicles -- from its overhead camera to its unit building mechanics -- resembles a real-time strategy game. The adorable characters and familiar Star Wars iconography could have made this free-to-play affair a worthwhile introduction to the genre for newcomers, but for a game with all the trappings of a strategy title, it curiously lacks any real strategic decision-making.

Angry Birds Friends brought the fowl-flinging sensation to Facebook, and unsurprisingly, it proved hugely popular in that format. Now the socially-connected spin on the franchise makes the return trip to iPhone and iPad while maintaining the distinct, free-to-play approach that defined that browser-based take. On a platform that already hosts five distinct Angry Birds games packed with several hundred total levels, the prospect of playing in one six-stage tournament per week may not seem remarkable, but it's the competitive aspect that puts an interesting tweak on the usual formula.
