In my opinion, a good Game Sage is a regular player who should be able to assist players with different issues, make sure that the players/customers are satisfied. Basically, make the game better by helping people and Game Masters, reporting people who ruin other people's time (harassment, flaming...) and try to create Events so that the people can stay amused. Good Game Sages should always stay positive, patient and keep stuff confidential.
