Rebooting may not be the right word. Let's say, ending one campaign and starting a new one, with a continuing core of old players and some new blood.
How do you reward those that have been there from the beginning without "shorting" those that are new to the group?
I was thinking same world, different area, move the timeline down - so either a political / family / historical connection or two or a passed down family heirloom for those that had played the first campaign.
I'm not totally sold on either, but I would want to reward those that have stuck with the group from the beginning.
This is all assuming that I do a reboot / restart / new start of the campaign. I might just pick up where it left off, but as that is getting further and further back in time as we playtest A&A (and we've missed 2 weeks to hangover / work on my end) I think it would be simpler and fairer to the now expanded group to start anew when we get back to playing a regular campaign.
How have you / would you handle this type of situation?
