I understand you're point about the, nasty raider type lots...but what about the other factions, the "NCR Happy Guys" for example... It still could be nice to have a few flowers for the peace loving factions, for example i'm working on setting up an in-game news channel, mainly full of passive characters trying to spread news, and report on attacks, interview the victorious....Sure...we're going to get killed lots but the motto will just have to be really motivating...if you have any ideas let me know.
But not everyone in fallout is out to kill, kill, kill. Some of us want to make the wasteland a better and more civilized place.

Also with the fruit and fibre plants, that is a good idea but the dev's might say no as if there was that much useful stuff available so easily the bases wouldn't be worth as much.
