The two games that I ran, Mobile Frame 0 and Pirate Wars, both went very well and I think there is likely enough interest for additional games. I'd certainly be wiling to play as would several others I know.
The game was quick and as getdamonkey noted, it was a bit of a learning experience. From my experience running games at conventions, this is the way it always goes and it is just something that needs to be accounted for. If you can, try to pair experienced players with novices to speed things along.
