I went to Gen Con this year and there were a few video games there, all of them had a theme that was conducive to the Gen Con envirionment.  I didnt' really feel that Neverwinter Nights 2 or Stronghold Legends didn't belong, they are both games I have been looking forward too, as I play both PnP and PC games, especially Neverwinter Nights 2 as its based on a PnP game.  Now do I really want to see the NFL Madden preview game, or a preview game for the next big gaming console, no, I have no desire to see that at Gen Con.  If I wanted to see that I would go to PAX or a similar Con.  So I hope they keep Gen Con the way it is, a smattering of the video games that were there didn't hurt anything, but I would hate to see the Gen Con environment change anymore than what it has already.
