this interesting article at Gnome Stew about switching between game systems within the same campaign.
Dave, would you be interested in perhaps opening up your world to other campaign possibilities using different game systems in this way in the future? Do you plan on sticking with the current ruleset when we return to the Badlands, or do you plan on doing some rule tweaking? What happens when our PCs get over sixth level and our NPC flunkies start to simply get too weak to make any sort of difference in a battle? Will we have the option to hire more powerful NPCs?
