Wish I was going.
From the announcement:
Gioconomicon.net has released the update for the FREE Android application that helps you keep track of your purchases at the next spiel fair in Essen!
"Take with you the interactive list of the new games presented at the Internationale Spieltage SPIEL 2014. For each game you'll find information on its publisher's booth."
This App's goal is to help you find the games you want to buy at the Essen Spiel 2014. It will also allow you to share info on the games you seek or buy with other users, and to compare these statistics with Boardgamegeek's wished or owned.
Gioconomicon.net is an italian webmagazine focused on games, and it's staff will of course attend Essen!
