The complexity of serious games requires large efforts for their development. For the development of serious games teachers mostly use commercial game engines. One of the important parts of game development is a selection of appropriate development tool. Due to the range of available tools the choice of platforms for serious games is a challenge, whose selection often has considerably different goals and technical requirements depending on context and usage. The aim of this paper is to propose criteria which should be considered before selecting a game engine for serious games and shows results of a comparison of evaluated most popular game engines.
