I realized that I never got around to posting this idea, lo! these many years. I toyed with:
- No "Reveal Map."
- A "zigzag" of Tiles, using impassable terrain, with the # of tiles = # of turns before appearance, with a full stack of "Barbarians."
- Each Barbarian group is a Civ with:
- An "Invisible" City, which can only build a single Thing timed to be finished when your Hordes enter onto the map, proper.
- Barbarians cannot build Settlers.
- Use the "Sub Bugs" to trigger wars.
