8 players with me introducing 7 newbies, including a pair of lads 9-10 or so. After the first round or two everyone was pretty much on auto-pilot and I tossed a game with a late-comer myself. Everyone except the late-comer and myself played 2 games and we wrapped up after 4 hours.
Not bad at all IMO, but, I am not sure about using this at a convention. I think I may try a set of more scripted scenarios for our convention this summer. Maybe have "pre-built" teams to choose from? That seems to take alot of time. Once the battle start, it rolls fast. Still thinking it over in context of a convention/intro game...
