I'm probably going to the Gamescom in Cologne this year, the biggest games event in Europe. It was usually in Leipzig, but since last year it's hold in Cologne. I'm looking for an hotel today, and will then go there from Saturday until Sunday. It's only 200km for me, and as my girlfriend likes to travel, wherever that is, I will probably go. I also will make some nice pictures.
