Background Info: the last project we worked on needed basic 2D functionality (sprites and animations) and SpriteKit was born to fill this need (http://www.youtube.com/watch?v=cabAr2CdLmc). It has no fancy editors and was really made to fit a specific need and as of yet it has not been extended much further than the video shows. Something a bit more full featured is required for a new prototype and instead of spending a bunch of time extending SpriteKit we went on a search for alternatives. None of the below frameworks are perfect and they all have pluses and minuses. One thing SpriteKit had that none of the others do is automatic texture selection based on screen resolution. That is one thing I would like to see incorporated in every 2D framework and it kind of surprises me that it isn't one of the first features added when making a 2D framework.
