G-factor Portability in Game Development Using Game Engines

Many games today are developed using game engines. This development approach supports various aspects of portability. For example games can be ported from one platform to another and assets can be imported into different engines. The portability aspect that still remains underdeveloped and requires further examination is the complexity involved in porting a ‘game’ between game engines. In this work the game elements that we aim to make portable are: game logic, object model, and game state which represent the game’s brain. These are referred to as the game factor (or G-factor). We describe how a typical game development approach using the Torque game engine makes the G-factor dependent on the engine and we contrast this with a new approach which enables G-factor portability between engines.
