Unity is ideal for developers with computers that do not support 3D-accelerated graphics. Factually speaking, Unity-2D is almost exactly the same as its 3D counterpart, albeit without the attractive graphics and overall look. You can create 2D and 3D content separately using the Unity game engine. Unity can include 2D and 3D elements in the same project or enable a 3D game to simulate a 2D view in 2.5D.
