FIFA 20 is currently only $54 if you have PRIME as there is a $5 discount at checkout prior to the release date which is the 27th September. Probably the cheapest price you’ll see for a couple of months for this game.
All three other games have been reduced to $51.99, not sure on the expiry but really good price for Donkey Kong. Tennis Aces has been this price before and Kirby Star Alliances has been $49 at Amazon previously. Still good prices for all these games.
