I saw this happen last week and it bothered me, so I made a video about it.
As a Game Master, you're the master of the game. Don't go power mad, don't hog the spotlight, and don't betray the players' trust by treating them like C-list supporting cast members in your pretend movie!
p.s. Why aren't you playing Alpha Blue... or new and improved strip Alpha Blue?!? Want to give the sleazy sci-fi RPG a little try? First time's free!
