Binding of Isaac is probably up there because two of the more popular streamers of that title (Richard_Hammer and CobaltStreak) just held a tournament for it that ended on Saturday. It was called Balls of Steel and it ran for like a month and a half, with the final rounds taking place Saturday night. So, I'm guessing people are still riding on the hype of that tournament.
Destiny always has a lot of viewers, especially with its two biggest streamers, Professor Broman and King Gothalion. I didn't think Payday 2 or Black Ops II were still that popular, despite the newest edition of the former releasing a week or two ago.
