No matter how many times I go to Gen Con I start getting excited about a month out. Going back and reviewing games, shopping lists, etc. helps work some of that out and this year I've added Nelly's 2016 videos (see below). If you've never been this may help show you the scale and pace of the Con for those of you who attended last year you may see yourselves.
