So, recently I was looking through the ethics sections of the civilization, and noticed the REQUIRED entry mentioned on the wiki wasn't in use. I got curious to see what effect it had, so I did some !!science!! on it. I opted to change the ethics entries of every single entity to make nearly
everything required. While my find-and-replace job did miss the few instances of NOT_APPLICABLE and PUNISH_REPRIMAND, and somehow replaced MISGUIDED with REQUIREDUIDED (which seems to have had no horrible buggy effects, suggesting it ignored this entry), everything else was set to required.
So, after generating a world like that...well, for starters I've uploaded it to my dropbox to share.
https://dl.dropbox.com/u/89427928/region2.zipAs for the effects found so far?
First and foremost, I can't tell for sure from viewing Legends mode if it has any different effects compared to ACCEPTABLE. There is however plenty of entries of humans, dwarves, elves and goblins all murdering, eating, and abducting each other, most of which requires the "show all events" option be enabled. Killing and eating sprees are repeatedly listed as "rampage" events, likely because the only other events I've seen of creatures making enemies of civilizations and committing wanton murder are by megabeasts. Curiously, changing the theft ethic has had no effect on thievery events, as the kobold ITEM_THIEF tag seems to be the only thing determining that, despite the wiki's claim.
As for adventure mode, it seems that your starting civilization may or may not be hostile to you. I've yet to have it happen, but a friend I sent the file to said it happened to him. I soon opted to see if making theft required affected whether stealing would actually piss anybody off, once I found a shope I actually wanted to steal from. To my amusement, grabbing a better sword was met by apathy by everyone. Going back in the store resulted in the shopkeepers telling me all about what that sword is like, then just ignoring the fact I went out the door with it. The game refused to let me fast travel out of town at that point, however. And upon entering the keep, an elven "sacred paper" announced his desire to kill me, and apparently he killed another person earlier. And then everyone starts getting all murderous with me for self-defense.
And then I remember the huge open market right outside the keep. Aw shit.
As for fortress mode, I've yet to test the effects of this idiocy. Note that there are some earlier mods I made to it present, cheating with emotionless dwarves and a few reactions to get free stuff. Hopefully the NOEMOTION tag shouldn't ruin the Fun.
