Nothing particularly wild on my wish list. For me, the dream is largely about campaigns that I don’t have the time or resources to run, because of real life getting in the way.
I’ve always wanted to run something in the vein of the Great Pendragon Campaign (though maybe not literally the Great Pendragon Campaign) — epic, multigenerational, and set against the backdrop of sweeping change — but it’s hard enough to manage scheduling and people’s short attention spans (mine included) just for short campaigns or one-offs. Something that might last years feels impossible.
My other dream is a proper West Marches-style campaign with dozens of players exploring a territory. I love the idea of stretching my worldbuilding muscles and creating something huge, cohesive, and mysterious. But I’ve had trouble getting the large and self-motivated group of players that requires, and I can’t imagine having the free time to spend creating the sort of world that would make running a West Marches-type game fun for me.
I think as a designer and player, I’m almost always trying to find ways to generate the feeling of these two ideas in a lighter, more accessible package.
