Cons
Con Slow
Everything takes ages..feels like Unreal 4
Con Lack of user-interface
Although you can customize a lot, the user-interface does not show that. But plans are in place to improve this with some front facing GUI into the LUA scripts so you don't need to code as much.
Con The documentation is not very extensive
The documentation for GameFlow could use some work. It's not very extensive and it hardly covers everything needed to know to build a game.
Con Performance could be better for 2D
Performance can be a real issue with 2D games. Unity 3D is actually a 3D game engine, and drags a lot of overhead with it.
For mobile, one could never achieve the performance of more specialized 2D engines with Unity3D.
