Our GM told us we're the first group that didn't finish his scenario in one game session (out of four he run it for).

Um... Achievement unlocked?

@tomo different groups take different approaches. I've run Big Trouble in Little Soho for four groups now, and every one of them has played it out differently in terms of story and play time.

Yeah, but in our case is that we've known each other for years and our games are more social chatter than actual roleplaying.
