This article explores existing attempts to design a comprehensive and complex taxonomy framework for an educational business game intended to categorize and evaluate various properties. The identified missing elements in the current proposed taxonomies were used as a starting point for the design of a new category that addresses the game's educational properties. The content of the proposed taxonomy category is presented and the properties selected are explained with regard to their merit in achieving the learning outcomes. The usability of the new category is illustrated with an assessment of two use cases, that is, simulation games taken from the area of project management. The results obtained with a survey and a teacher's and student's evaluation are presented and discussed.
