Concerning ROP abuse:
Here's the situation. I'm playing America, right next door to England. Because England is so big and has so many troops (and they're all moving through my territory to get to various wars), I signed an MPP with them. I also did this because I wanted to get their navy to kill off the Chinese navy, as I'm currently engaged in an infantry war (for the sake of saying I conquered a civ with just Infantry) and those frigates bombarding my coast every turn is annoying. Unfortunately, China got Korea, formerly my ally until her size and location no longer hepled me, to declare war on England. When England attacks, I get dragged into the war. Unfortunately, my massive fleet of galleons were in Korean waters, so I got an ROP hit.
The game is at Monarch, we're in the 1500s and I'm currently researching Steel, the ToE= Atomics and Eletronics line done. All victories except for wonder and histograph are disabled (except for diplomatic, as I have to have the UN for a wonder victory) are disabled, because I really want a histograph win, as I've never had one before. How long will it take the AIs to forgive this accidental tresspass, or do they ever? I never ROP rape (stopped once I learned what it was), so I don't know what the limits are.
