The Nationals has a forum. It's not exactly buzzing at the moment naturally, but Sheffield folk are starting to look at what people signed up for it want. I suggested some hint of games that might actually run in a given category, where practical. (A&A 2010 was pretty much set by December 1st, and given a deadline I could have come up with at least a system of choice earlier.) Which got me thinking, which Nationals games would I have gone into based on game-specific blurbs a la Conpulsion rather than going in blind due to the choosing categories...
( A line or two about twenty-odd games. )So, on the whole, yeah, I'd like to see the premise of a game or at least a system rather than going purely by category.
Of course, this isn't always possible or practical if, say, you have three groups and three GMs. I can well imagine Game A filling up while Game B languishes, and prepping a second adventure probably ain't gonna appeal to every GM...
