   ABSTRACT     = {Game engines help developers create video games and 
      avoid duplication of code and effort, like frameworks for traditional 
      software systems. In this paper, we explore open-source game engines 
      along three perspectives: literature, code, and human. First, we 
      explore and summarize the academic literature on game engines. 
      Second, we compare the characteristics of the 282 most popular 
      engines and the 282 most popular frameworks in GitHub. Finally, we 
      survey 124 engine developers about their experience with the 
      development of their engines. We report that: (1) Game engines are 
      not well-studied in software-engineering research with few studies 
      having engines as object of research. (2) Open-source game engines 
      are slightly larger in terms of size and complexity and less popular 
      and engaging than traditional frameworks. Their programming languages 
      differ greatly from frameworks. Engine projects have shorter 
      histories with less releases. (3) Developers perceive game engines as 
      different from traditional frameworks. Generally, they build game 
      engines to (a) better control the environment and source code, (b) 
      learn about game engines, and (c) develop specific games. We conclude 
      that open-source game engines have differences compared to 
      traditional open-source frameworks although this differences do not 
      demand special treatments.}
