Do you have to take a break and rebuild the board everytime you enter a new room
Yes. It doesn't take very long though and usually we leave out details like terrain unless it is important. It's usually 20-50 seconds. I loosely base them off maps from the guidebook for that area, or just make them up.
So we've been playing the 4E Forgotten Realms Campaign, and so far we robbed a guy and got kicked out of Loudwater, found a guarded portal and killed the guardians, then decided not to enter the portal after all, and healed a sick child in a poor village in return for archery training.
oops, didn't mean to bump this
