I've played Fluxx in groups from 2 through 10; Zombie Fluxx seems to work even better at the ends of that range.
The boxes of all the Fluxx games say 2-6 players, but how well do the games play with 7+ players? I have Zombie Fluxx and the regular Fluxx, is there anything I can do to make the game play better with more people? Does anyone with experience of 7+ player Fluxx have any advice? I know combining different versions can often make it impossible to fulfil some goals, but I'm still curious.
