I really want to go to Essen some year. I've done Gen Con many times now (something like 7-8) and think it'd be cool to go see some of the conventions over in Europe. Salute is one and Essen is the other. This year, Mayfair Games will be present and they'll have some of their game designers with them. If you'd like to meet them and get an autograph, they've posted times for that at the show.
You can go find them in Hall 1 F-133. The designers and the times they'll be in the booth are:
Chris Baylis: Thursday 1:30 – 2:30 pm & Friday 1-2 pm
Andrew Bond: Friday 11am – 12:30pm
Fréderic Moyersoen – Saturday 11am –12pm
So if you'll be at the show, be sure to stop by and say hi.
