You are provided with the abstract of a scientific paper and the abstracts of the papers it references. Your task is to write a Related Work section for the main paper. This section should concisely summarize and integrate the key points from the cited abstracts, reflecting how they relate to the main paper's contributions and context. In your summary, use numerical citation markers like [1], [2], etc., to refer to the corresponding papers.

Main Abstract:
Multiplayer computer games play a big role in the ever-growing entertainment industry. Being competitive in this industry means releasing the best possible software, and reliability is a key feature to win the market. Computer games are also actively used to simulate different robotic systems where reliability is even more important, and potentially critical. Traditional software testing approaches can check a subset of all the possible program executions, and they can never guarantee complete absence of errors in the source code. On the other hand, during more than twenty years, Model Checking has demonstrated to be a powerful instrument for formal verification of large hardware and software components. In this paper, we contribute with a novel approach to formally verify computer games. We propose a method of model construction that starts from a computer game description and utilizes Model Checking technique. We apply the method on a case study: the game Penguin Clash. Finally, an approach to game model reduction (and its implementation) is introduced in order to address the state explosion problem.

[1]: It is typical in the domain of digital games to have many development 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 results 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 Development (MDD). Also, we discuss and demonstrate the several benefits of applying MDD in terms of rapid prototyping of cross-platform games, and their evaluation by means of static and dynamic verification of the game's logic properties.
Software verification is a very active research field. However, the area of games has been only partially investigated. In [1] , a case study of verification of role-playing game (RPG) is discussed. The authors use the Algebraic Petri Nets Analyzer (ALPiNA) model checker to verify reachability properties of the model, represented by the Petri Nets. The results of the work are very promising, however the game model has not been formally defined, and the necessary steps for constructing it from the game specification were not explicitly discussed. Moreover, examples of more complex game properties have not been studied.
