The current study presents an adaptable light game engine, which is used to produce interactive educational settings focused on cultural heritage. The tool is implemented using inexpensive and open source technologies. In this paper we first discuss the architecture of the application and we then present two games developed by using the proposed engine. The produced games are multi-user and support the collaboration and communication among learners and among learners and instructors. Learners earn marks, badges and certificates as they study the material and complete the quizzes. Various evaluation experiments have been realized to understand the suitability of the produced content in educational activities. The evaluation results of the authentic educational actions were quite positive and supportive by both students and teachers.
