The last eternity a 3D role-playing game with a cross-platform development

This paper describes a cross-platform game engine for PC-based and iOS-based mobile devices. The purpose of this paper is to demonstrate a case study for a game developer and a game designer on the mobile platform. We discuss an implementation case-study on the game `The Last Eternity´. We present the wrapper around OpenGL|ES and OpenGL for PC, a structure of 3D game engine, a simple script design within the game engine, and a design and structure of the game. The game design, limitations, technical problems, and API are solved and discussed in this paper.
