Of course my idea doesn't really solve anything, but it would be an interesting competition none the less. Say for instance Matt Hall decided to challenge Donald Hayes to best Arcade/MAME gamer out there. I have an interesting way to settle it. Have a game off challenge.
Here is how this would work.
Each person has the choice of a game they are great at, and the competition goes until one person beats the other person in their choice of game.
So an example
Donald Hayes would pick Centipede. He, and Matt Hall play one game of Centipede, and if Donald Hayes wins then Matt has to respond with his choice. Most likely Matt would choose Shock Troopers, and if Matt wins, then Don has to pick another game. Most likely for Don he's picking something like dig dug, or Super Zaxxon. This would go over, and over, and over again until one person picks a game, and loses to their competitor. Then that person would be declared to be the better player.
I don't know if anyone will actually use this idea, but I do think it's a good way to settle whose the better gamer.
