Game changer 

The one that always moves the goalposts to their own game to keep people from finding a rhythm. If you figured out the difference between what really happened and what a history book tells you happened, the game changer would change history. If you discovered the meaning of life, the game changer would change it to something else just to keep you arguing with his/her argumentative natured self.

It is the game of a game changer, it always has been.

Game of Love Chicken 

When two people think they might like each other but they pretend not to because each is waiting for the other to make the first move so neither has to feel embarrassment if their feelings aren’t reciprocated.

Jack and Jill CLEARLY like each other but they’re both too shy to say anything, they’re playing a game of Love Chicken.

previous game advantage 

the advantage of playing the previous video game in a series, giving you an edge in the sequel over other players that are new to the series.

BC2 was awesome because anybody who had ever played a battlefield game before pwned everybody who hadn't. I had a previous game advantage.
