Education and Game are the main keyword for the future society. Many countries are taking notice of these to improve the competitive power of their countries. Educational Game is not Education for Game but Game for Education. By the way, there are many definitions for the Educational Game and many discourse about the relations between Education and Game. It is necessary and meaningful to discourse about setting of relations between Education and Game in this point of the time. Generally, some former studies are focused on functions of Education using Game but this study tried to back to the basic with discoursing about the definition of Education and Game itself. Finally, this study drove the definition of Pedagogical from discourses among Education, Game and Educational Game. Educational Games are going to be developed plenty but we get some problems for adjusting the balance between the goal for the Game and the goal for the Education or blending game elements for the fun with cognitive knowledges which are learned during game play. Pedagogical Game can give some suggestions to solve these kind of problems or to make you back to the basic discourse between Education and Game.

In Korean pedagogical discourse involving young learners, boundaries in pedagogical activities are signaled by the teacher’s style shift that utilizes a range of sentence-ending suffixes that index different degrees of formality and politeness. The shift from the use of the informal polite form -(e)yo to the use of the informal non-polite form -a/e in teacher's talk is contextually motivated by the need to address contingencies associated with a range of classroom management tasks of dealing with individual students, e.g., matters related to disciplining, advising, encouraging, etc. The shift to the formal style characterized by the formal polite forms -(su)pnita/-(su)pnikka takes place in the context where the teacher highlights his/her instructional focus, explicates subject-related knowledge, and/or marks a boundary in pedagogical activities. In young learners' talk in class, the formal style is used when they make a report or presentation related to group activities or produce a response whose upshot draws upon the textbook content, often in the context of reciprocating the formality indexed by the teacher's subject-related questions. Young learners' use of the formal style tends to be limited to a single-shot response, which constrains the extent to which they can sustain participation in subject-related classroom activities. The findings suggest that young learners could benefit from being allowed to use the informal style more freely in dealing with at least some 'formal' aspects of the way subject knowledge is organized in class.
