Even when learning another language, we memorized lists of vocabulary, grammar forms, idioms, etc. The teacher was above us, we were supposed to be subordinate. If you want your learners to join in the fun of doing a game, then you will have to lovingly encourage and help them to get up and join the others standing ready to play. You can use children's games and do things children enjoy, without becoming childish. We all have the child still in us, so use this natural relaxed atmosphere to promote language learning.
