The original map I whipped up for my last (not dead yet even though I've taken an extended hiatus due to, you know-life) campaign. The funny part is that I had envisioned the campaign to be an explorative/hex crawl one, but no plan lasts after contact with a good gaming group. I'd designed a few faction/politics hooks, and that's what really got them. They maybe explored 20% of the area around them, and it lasted a year before I moved! But everybody had fun, and that is the only thing that matters.
