Next campaign to run...

So GASPCon has come and gone, games were run and played but its time to move forward.

Here are the important points
1. It will be run at GASP Gamesdays
2. It will be some form of Fantasy (depending on how liberal you are with the Genre)

So heres my short list of concepts
A) The party collaborates to create the world before we create characters. Everything from available races to the technology level of the era played in to what god(s) exist is completely on the table. I take the world created and spin out adventures.
B) Running TSRs big Night Below campaign box using simpler rules - like Rules Cyclopedia or Spellcraft and Swordplay.
C)Campaign level game - ala Birthright or Council of Wyrms. Create a nation and a character, and run both.
D) Something Weird - ala running a mesoamerican or arabian nights game, something different.

Anything sounding good?
