I know it would take a lot of coordination with a con's gaming director, but I think it would be cool to pull off.
What if you ran two sessions, both named the same like Frat Boys vs Aliens, but one session's players played the Frat Boys, the other the aliens and then they would officially clash at the end of the adventure.
see, fratboys are always fun to play, since my frist real experience with qags was "frats vs. undead nazis" which leighton ran at origins '06 i think.
if i was to do it, i would definately do frats vs. C.H.U.D.Z. with players being the chudz. however, the more i think about it, perhaps the best of both worlds could occur here. half the table as frats, the other half as chudz. like i said, i'm still kickin the idea around.
loco, i also like the idea of running the adventure as two seperate entities, but ideally the same game with diffrent vantage points. just wanted to add that to my previous post
