Write code to determine the mechanics and game play of new software; Program many aspects of video games such as graphics sound interface scripts etc. Research the demographics and statistics relating to the game to determine type of gameplay to use; Trouble shoot game programming to ensure no mistakes are made. Mobile Game Spawning Algorithm. -> This example. 
Unreal Engine Framework. -> Video of this code running. -> See the source code here.
It has its own physics engine, a script editor, built-in animation system, a GUI for editing animation, video playback, audio system, multithreading, etc (too many to meaningfully list).

The Text Adventure Development System, or TADS for short, lets you write your own interactive fiction using a language specifically designed for writing text adventure games. Originally sold as shareware in its earliest incarnation, it is now free. The system has been used to develop numerous commercial games. Like many programming languages, it is similar to C/C++ (with even complete support for the ANSI C macros), but has features intended to make it easy for you to develop text adventures. Besides text adventure games, you can also use it to write your own 'Choose Your Own Adventure' type of games or Role Playing Games (RPG). The software uses as its layout language and lets you integrate graphics, animations, music, sound effects, hyperlinks, etc, into your game.
