That's amazing, Aramax! What an epic story!
Our high school AD&D campaign was set in a homebrew world, but I found I was enjoying RuneQuest far more than AD&D, and so plotted to finish it once and for all. It took about two years; first they were propelled into Lovecraft's Dreamlands and went on a long journey there, and when they re-emerged hundreds of years had passed and the land was devastated a la Thomas Covenant. They managed to defeat whatever dark lord (TM) I had cooked up, and became the gods of the new world.
Campaign, OVER!
I didn't touch a D20 until well into the 3E cycle, and have been playing some form of D&D again ever since.
The old campaign is still alive in some form though, my efforts to kill it were not successful; the player who enjoyed it the most recently passed me the script for a graphic novel he is working on, along with the map. The characters and places were very familiar, but also much improved. You can't kill an idea, it seems.
Thanks for sharing, Aramax, I hadn't thought about the long road of gaming like this for a while.
Cheers,
Mark
