Ghost Fightin' Treasure Hunters!
This game won the prestigious Kinderspiel des Jahres award in 2014. I almost imported a German version back then but decided against it. I kind of forgot about it until I saw it on sale for $20 a few years later in English.
Four players need to navigate a haunted house as a team and gather up the gems inside, eliminating ghosts along the way. As every turn passes, more and more ghosts spawn throughout the house. If 3 ghosts spawn in the same room, it is haunted. A haunting takes 2 players to eliminate it. If 6 rooms are ever haunted at once, game over.
This game ain't easy. Poor dice rolls will tie up characters and allow rooms to reach haunted status faster than your team can cope. You have to balance fighting ghosts and gathering jewels. Once the scales start tipping against you, the game escalates exponentially. We lost one of our games tonight with my wife on the doorstep to victory, a single square away from the win.
The game is colorful, thematic, and has high production value. It's always a nail biter and we love our cooperative games. Highly recommended, especially if you have kids.
