There a lot of plugins to handle 2D (2.5D) games on Unity, I am currently using 2D Toolkit ($50) for sprites and it's awesome. I also recommend to check RageSpline and RagePixel, this tools provide features totally integrated with the IDE and really easy to use. I haven't try CoronaSDK but I can see a lot a potential in 2D games with Unity, not just 3D. I fact, you can see a lot of nice 2D games in his showcase, for example Zombieville USA and Max & The Magic Marker. - http://unikronsoftware.com/2dtoolkit/ http://unikronsoftware.com/2dtoolkit/ - http://ragepixel.com/ http://ragepixel.com/ - http://ragespline.com/ http://ragespline.com/ - Max & The Magic Marker http://goo.gl/H9Hl0 http://goo.gl/H9Hl0 - Zombieville http://goo.gl/fzZP0 http://goo.gl/fzZP0 - Showcase http://goo.gl/g4uux http://goo.gl/g4uux
