Under Rules - Civilizations - Build Never - Def. Land Units
The AI will still build defenders occasionally, but not as many.
Not certain, but I think the formula involves pi and the phase of the moon
I'm pretty certain that it ain't affected by map size.
I tried getting AI to drop units that were only defensive AI strategy and artillery AI strategy, but it wouldn't do it (for something like 100 turns straight, then I stopped). Offensive AI strategy units it would airdrop like crazy. So I think it must be hardcoded.
If you take Market Garden, the goal was to make a surprise attack, take a few key points and hold them until the reinforcement arrive.
Defensive paratrooper is not that strange.
Not because of the paratroopers, but because
1) for Dien Pen Phu, the AI was not programmed by Firaxis and actually used artillery
2) For Market Garden, Montgomery poorly design the scenario, he should have given 1more MP to the tanks so they could arrive in time.
If you uncheck fortify for a unit
a) It cannot sentry anymore
b) The fortify button is not there... But you can still fortify it using a right click and the contextual menu
--> Removing the fortify is useless
What was very annoying in my tests if if you remove fortify, the unit cannot sentry.
So you must pass it every turn and tell it to do nothing.
This is quickly extremly boring.
Is it documented anywhere that F12 lets you crop maps in Firaxis's editor? I just saw that today in a thread, which I didn't want to threadjack, and had no idea Firaxis's editor supported that before, nor do I see it in the menus or mentioned in the Help files. I'd thought it was only in Steph's editor. It doesn't seem that stable in Firaxis's editor, though - I was able to get it to crash when cropping pretty easily, including an ill-fated attempt to expand the map by cropping with a negative start.
I downloaded this thread and couldn't find "F12" or "crop" mentioned in it, either. Maybe it should be added to the first page or linked to somewhere off of the first page?
