Gold Box Deal of the Day.
Amazon's deal of the day is for a bunch of board games, almost all of which have a good reputation. A few descriptions:
* 7 Wonders, a card-drafting and civilization-building game. Not hard to learn, supports up to seven players.
* The Resistance, a social/party game where players try to figure out the traitors, similar to Werewolf or Mafia. Wil Wheaton and co. played this on Tabletop.
* Forbidden Island, a co-op or solo-play game where you try to survive on a deserted island. Has a reputation for being tough as nails.
* Flash Point Fire Rescue, a co-op game with firefighters rescuing people from a burning house. Easy to learn, good with families.
* Dominion, the first "deckbuilding" game, where players build a Magic-style deck over the course of the game. One of the most popular strategy games in the world.
