In this regard, the most notable feature of tennis is that every match is a mini-tournament. It doesn't matter whether you lose the game 40-0 or after the 5th deuce point, you still just have to make up one game. Similarly, the score of the first set doesn't matter; only who wins. This periodic levelling of the score seems to make it more engaging somehow.
