You haven't played Virtue's Last Reward, have you Bliv? That's just the name of the main character. She ran a random stretch of the Ambidex Game that takes place in the game with names from the RP as placeholders at one point, but that's the only thing I mentioned Sigma in...
In other news, I've been playing the new Fire Emblem for about 4 days straight, after it came in four days late. I'll see you guys next year.
