We took a pass last night, maybe some other night this week.
I wasn't sure where to cap the levels, I was reading Demo's stats in the MM (or MMII, can't remember which one he is in), and that sounds about right target wise for levels, I think I was hoping for ~15+ I do have the B/X Companion by Jonathan Becker so I can go to 36 if I really want to :)
I think the challenge for me will be how to make sure the Xp keeps the progression on track for each of the modules to hit the 1-1.5 million xp target by the end. And add to that, while most of the monsters are in the older editions, sometimes their challenge rating/level is off.
But that is part of the fun I guess :)
