It can be said that chivalry affected the characters when the Knights exhibited their behavior. The Green Knight challenged the knights´honor and so Sir Gawain asked the King to accept that challenge. It seems that he wanted to show his loyalty (value of Chivalry) to King Arthur. Later on, the Green Knight promised to keep his word (value of Chivalry).
Within The Tempest it is demonstrated that contact with native populations is rarely an even exchange; the native people are usually exploited in some way. This is demonstrated by the way that the "invaders" in the form of those who are shipwrecked at the beginning of the play attempt to change the islanders, little suspecting that one of them is the usurped Duke of Milan - now in the form of the wizard/magician Prospero.
To some extent it could also be argued that Prospero himself has already changed the nature of the island by being there. He has introduced magic, captures the monster Caliban and lies to his own daughter (allbeit it to protect her).
