This thread is perfect. I've had an idea I'm stuck at developing for the past 2 days. After playing a long, drawn out 100k game, I came up with this:
__________________________________________
modified AW - Destroy all Wonders!
Civ: Japan
World: Continents or Pangaea
Map Size: Tiny to Standard
Difficulty: Regent to Monarch
Game Rules: Whenever a wonder is built, you must declare war on that Civ and raze the wonder city. If you have not met the offending civ yet, declare war when you first meet them. We can't allow these unholy manifestations to exist! All wonders must go! Ision is our great teacher

!
__________________________________________
Japan being Religious will allow the quick switch from anarchy from on and off warring. Obviously a conquest or domination victory is good here. Map type and whether we can wage other wars, and whether to keep warring with the same civ (after razing wonder city) I'm still debating.
Feedback appreciated.
