Never tried this with 8 players. Is this one game where the more the better? Since I have 8 people expressing interest in playing my new copy of the game, I'm wondering if 8 players is advisable or not.

Hilarious.

I played with my regular group of 8 and had a great time. The sub breaks *incredibly* fast, but gets fixed equally fast. One result is someone usually has a good item for whatever crisis is most pressing. We ended up with the sub sinking, but it was a very near thing. Scales very well IMO.

I've played a 6 player and an 8 player. Both were excellent.

I played with 7 and found the game play too slow with people getting easily distracted waiting for their turn. Just my 2 cents.
