Now who are these five?
Come, come, all children who love fairy tales.
Can anyone see why we can't add additional cards to the Market? I would say add 4 more making a diamond array. I can see it would add a little time but otherwise there would be more variety. Any thoughts?
You'd change the game slightly. My take on this (and all rule changes) is: Do it. If it makes the game more fun for you, then you were right. If the rest of the world tells you you're stupid, you're still right. After all, you're the one playing the game.
The only risk I can see you'll run is that "drawing cards from the deck" will take more time – you'll have more piles to fill out. Also, you'll get a larger selection, something which might nivellate the games.
