Anything involving action is always good. Students love to get out of their seats and play because they spend all day sitting down at school. Also if you show a lot of excitment and enjoyment with the game, that will rub off on the students. Don't worry about being nervous. It's more important to show that you are NOT nervous to the students as they will naturally look up to you
(and they don't know if you are new to teaching or not!)
