Gideros is a free and open-source cross-platform game development framework that enables developers to create high-performance 2D games using the Lua programming language. It offers instant testing on real devices through Wi-Fi, eliminating the need for lengthy export or deployment processes. Built on C/C++ and OpenGL, Gideros ensures that games run at native speed, fully utilizing the power of CPUs and GPUs. The framework supports easy extension through plugins, allowing developers to import existing code in C, C++, Java, or Objective-C and bind it to Lua. Gideros provides its own class system with standard object-oriented programming practices, enabling clean and reusable code. The comprehensive development environment includes a lightweight IDE, players for desktops and devices, a texture packer, and a font creator. Gideros supports multiple platforms, including Windows, macOS, Linux, iOS, Android, and HTML5.

Pygame is a set of Python modules designed for writing video games. Pygame adds functionality on top of the excellent SDL library. This allows you to create fully featured games and multimedia programs in the python language. Pygame is highly portable and runs on nearly every platform and operating system. Pygame is free. Released under the LGPL license, you can create open-source, freeware, shareware, and commercial games with it. With dual-core CPUs common, and 8-core CPUs cheaply available on desktop systems, making use of multi-core CPUs allows you to do more in your game. Selected pygame functions release the dreaded python GIL, which is something you can do from C code. Uses optimized C and assembly code for core functions. C code is often 10-20 times faster than python code, and assembly code can easily be 100x or more times faster than python code. Comes with many operating systems. Just an apt-get, emerge, pkg_add, or just install away.
