The RPG DSL: a case study of language engineering using MDD for Generating RPG Games for Mobile Phones

It is typical in the domain of digital games to have many de-velopment problems due to its increasing complexity. Those difficulties include: i) little code reuse in order to develop a cross-platform game; and ii) performing game’s verification through extensive and expensive tests. This of course re-sults in low productivity in the development (evolution and maintenance) of game solutions. In this paper, we present a domain-specific language (DSL) for a Role-Playing Game (RPG) product lines, which was completely built using a software development technique driven by high level abstractions—called Model-Driven De-velopment (MDD). Also, we discuss and demonstrate the several benefits of applying MDD in terms of rapid pro-totyping of cross-platform games, and their evaluation by means of static and dynamic verification of the game’s logic properties
