2D Cross-Platform Game Development Engines [closed]

Answer 1

If you have C# background. Have a look at Duality.

Duality is a flexible 2D game framework written entirely in C# – and it’s here to make things a little easier for you. It provides both an extensible game engine and a visual editor to match. There will be no need for a level editor, testing environment or content manager because Duality is all that by itself. And best of all: It’s free.

Here is my game framework Oxygine. It is open source modern hardware accelerated 2D C++ framework for mobile and PC platforms. Features: OpenGL(ES) 2, compressed textures, atlases, complex animations/tweens/sprites, scene graph, fonts, event handling, build tools, and others. Can be built on top of SDL2 or Marmalade SDK.

In the basis of the engine there is a scene graph, that is similar to Flash one. To be short, You can call this as Flash for C++, but more comfortable and way faster. Initially it was developed for mobile platforms (iOS, Android), but can be also used for PC games.

You also have ShiVa3D, a serious competitor of Unity3D. It uses Lua and supports many platforms from mobile to game consoles and web browsers.

Very intuitive to use and very nice UI to work with.
