You guys all played Survive. They sell the 5-6 player expansion for like $8 bucks (it's gives you all new plastic meeples for up to 6 players and some new tiles) but I can't really imagine that game with 6 people! 4 seems about right pacing wise, but I guess 6 would add a lot of chaotic fun. There's also that Squid expansion, but it sounds kinda bad. The rules as printed have the squid spawn/move on a whale's roll and they can pull dudes off the island and kill them. Sound crazy powerful. Neat looking SEAples though.
