I've been watching Indiana Jones and the Kingdom of the Crystal Skulls today, and I'm halfway through reading Lovecrafts Mountains of Madness.
I am currently overcome with a desire to run a pulp game. Either Trail of Cthulhu or Adventure!
Either would be acceptable, and would no doubt use similar set pieces.
I'm favouring Adventure! as I write, as it is a marvellous system that rewards creativity, description and ingenuity, and allows the players to directly affect the narrative. It's rawrsome. And great fun as well.
