Yep, it's Mailbag time again. In this week's thrill-packed installment: more on Sin, an open letter to GT Interactive, Requiem: Avenging Angel, Daikatana, John Carmack vs.Y2K, and of course, more. Hop on over to the April 11th edition of the Mailbag, and remember: I didn't make a single one of these up. Seriously!
