We played 1.5 boards so far with 5 people. I forget how long board one took, but board 2 is fresh in my mind so far. We are 11 games in:
5 Players: First Night we played for 11 hours straight with 4 games completed. Second game night was 10 hours with 5 games played. #3rd night was 6 hours with 2 games completed. Game 10 took 30 minutes. Game 11 ... it took 5.5 HOURS! It was the most intense, emotional, flipfloppy hell of a game i have ever seen in any risk board ever (And my childhood friends and I played a lot of risk growing up). I don't expect to ever see another 5 hour game of risk legacy like that again.
