I went to messiahdivine and cloquewerk‘s place last night and we eventually ended up playing Arkham Horror. I’m fairly convinced games like that were created by alien intelligences to test how much computation and grunt work humans will willingly do for fun. In the 2 hours before I had to go home, we got through 5 turns. I figure winning the game would take at least 50 turns. Granted, there were a few beginners at the table (including me) so later turns would probably be quicker but still, who has that kind of time? See also: ASL, in which you reenact world war 2 battles at painstaking levels of detail.
