Unity is a game engine that supports many the coding languages C# and C++ and makes 2D and 3D games. Unity was launched on June 8, 2008. I had been hearing about the engine for a couple years and recently decided to learn to use it. I currently am making a little strategy game involving making buildings to produce resources using a tutorial. I may update you on this but probably not. The language I am using is C# and I also happen to be learning that language too.
