For those who have played both, which game do you find is out to screw you more: Arkham Horror or Red November?

I think you're talking apples and oranges here, seeing how the games are so different. Arkham Horror is a much more involved and character-intensive game. Red November is faster-paced and nowehere near as involved, designed to be run in about one-third of the time required for your average Arkham Horror game.

That being said, I play both, and I'd say Red November's lethality level is higher, generally speaking. I don't look at it as "screwing over" the players; heck, gnome death is one of the most entertaining aspects of the game. In all my Red November games, I think our gnome crew has survived roughly half the time and died half the time, but the players have had fun every time.
