I'll be running IA at a local game convention in March, and having not played all of them yet, which would be the best/most fun campaign to run for it? The players will be a mix of seasoned gamers and neophytes, as most cons are. We'll have time in our session to probably get two or three missions in. I have all the sets and all the ally packs too, so there's no limit for which box we could use.
Thoughts?
