Not sure if this has already been discussed... Let me know if it has...
I just bought the second edition of A Few Acres of Snow where the rule book pointed out that the reason there is a second edition is because some players discovered a broken strategy for the British that the designer hadn't realized. So at the end of the print run he made a small tweak to two or three rules and labeled the next print run "second edition". He also brought this up on boardgamegeek and encouraged owners of the first edition to amend their rules accordingly.
This is basically the first time I've heard of a physical board game being "patched" a la a video game... And got me thinking about similarly "patching" Dominion with a set of house rules for certain cards. Here's some ideas:
=====update: includes ideas I like from others in this thread (& elsewhere)=====
- Black Market – Replace the first two sentences with “At the beginning of your buy phase, reveal the top 3 cards of the Black Market deck. This turn, you may buy these cards as if they were in the kingdom.”
- Bridge – Replace sentence with “While this is in play, cards cost 1 coin less, but not less than 0 coins”
- Coppersmith – Replace text with “While this is in play, Copper produces an extra 1 coin this turn.”
- Graverobber – Replace the first two words with “You may choose one:”
- Masquerade – After the first sentence, add “(If a player does not have any cards in hand, he takes the card passed to him and passes it to the player on his left.)”
- Moneylender – Prepend the text with “You may”
- Possession – Append the text with “A player cannot have two consecutive turns under the influence of Possession.”
- Scrying Pool – Replace the first sentence with “Reveal the top card of your deck and either discard it or put it back.”
- Thief – Replace the second sentence with “If they revealed any treasure cards, you may choose one for them to trash.”
- Throne Room – Replace the first sentence with “You may choose and Action card in your hand.”
