We have now had four full sessions of gaming, probably about 4-5 hours of gaming each. I started the campaign with the Finial Sanction adventure modified slightly for the full rules. Our sessions are not slow or bogged down and things seem to move at a pretty brisk pace. The players role-play well and interact well with the NPCs and each other.
So far after about 16 hours of enjoyable play I would say we are past the half-way mark of the Final Sanction game. My guess is that at our current rate it will take about 2 more sessions to finish Final Sanction. So that means about 27 total hours to complete Final Sanction with a group that does not waste much time.
I am curious about how fast other games progress in comparison to ours. I seem to recall somewhere it being mentioned that XP is generally awarded at the rate of about 250 xp per hour of play. This would mean that a 27-hour long adventure would net 3375 xp which seems a bit excessive to me.
