Tom's mentioned fantasy isn't his setting, I've had thought that something sci-fi/horror Rogue Trader would work for him. I can't imagine why Cody isn't interested in the game. Frankly I'm stunned I thought both of them would love this or Dark Heresy.
They say why they aren't interested?
Addition:
By the way, Ross, the Radical's Handbook source book for Dark Heresy just hit. Fucked up shit usable by PCs in that one.
