I've been a hero playtester from the begining,
and at Ubercon I had an opportunity to run WGP for the first time.
It was quite an exilerating experience.
One of the discoveries is that One Deck for 4 players gets absorbed rather quickly.
Mike will likely add this to the update sheet for the new rules once he has time to write them. but I made a rather happy accident at the game.
I gave the players their Deck but it had 2 jokers in it instead of one. (I pulled the 4 of diamonds and left that in the pack thinking it was the Joker) The additional joker allowed for more shuffling of the hero deck, which can be a problem especially if a player is reluctant to use his wild card waiting for the best moment.
As there were 4 players, the additional shuffling was a good thing.
