The game didn't go too badly. We missed ending the scenerio because of having to re-equip -- and we still ended up with a ranger without a melee weapon. But I think we all had fun.
I'm not sure how much was 4ed, my fellow players, or the nature of a con game, but this was a bit combat heavy for my tastes - 3 combat encounters in 3 or so hours, and not much role playing.
I also noticed the young players calling hit points "health." This seems to confirm that they have video game experience.
I may see about the 1ed game on Sunday, if we can keep Derrick occupied while I'm playing and robot_grrl is on a pannel.
