Unlike many games available, 7 Wonders is quick and is playable within 20 mins. You are also impacted by the person on either side of you, but less (if at all) impacted by the person opposite you, so a great game if you have 4+ people to play.
Ample ways to win, so tactics can vary.
Reccommended if you have a small amount of time to fill in between other games!
