=====Design heuristics=====
The heuristics have been organized along five **dimensions**:
  - [[#Game general design|Game general design]], which refers to issues related to the overall game design process.
  - [[#Control / Flexibility|Control / Flexibility]], which is a basic dimension of system usability, that with respect to the games considered in this paper, also refers to helping players to be aware of the effects of their choices on the game execution.
  - [[#Engagement|Engagement]], which informs on how to provide an experience that captivates the players, by providing hints on how to structure the game, which tools to adopt, etc.
  - [[#Educational Aspects|Educational Aspects]], which informs on interweaving of learning content into the game context, so that the game can have a valid learning influence on the players,
  - [[#Social Aspects|Social Aspects]], which concerns the interaction among the players, role allocation etc. (the underlying assumption is that social activity, e.g. competition, can act as a motivational factor).
