I suspect every GM has an idea on the back burner  for a campaign that they’d love to try sometime, but never seem to get around to.
Mine is a hybrid MechWarrior/BattleTech game where the PCs are all ‘mech pilots (and the RPG stuff is handled with a different system than MechWarrior, which looks awful), with the cool bit being that when they get into ‘mech battles, we switch to the BT rules. I’ve had that one rattling around up there for around eight years now, and never had the combination of time, inclination and group to try it out.
So how about it: What campaign concept have you always wanted to run, but never had a chance to try out?

As before, there will be a new post every day, but I won’t be able to respond to comments or reply to emails. I’ll be back with a full report next week — have a good time without me! — Martin
