Hello,
so I'm dusting off my disc just to play this overhaul and I must say, it really is awesome. This is really the one effort to rule them all. Thanks so much for this. I'm a landscaping and "decoration" buff, too, so I really appreciate all these changes. Also the creature management stuff, the drinking spots etc. This is just amazing. Way to go!
Not only that, but you seem to have acquired some very deep knowledge on the game.
I think you, Kratzean (another user of this forum) and Lant (Admin of bawsite.com) could make some magic happen to finally crack open this game and reveal all its secrets. Might I for starters direct you to the official script files that define basically everything in the game? They can be found here: http://bawsite.com/infodatsecrets.html
In one of them I found weather or at least "rain" effects, going from "moonsoon" with 100 Wetness and -3 Snowfall to "Blizzard" wit 0 Wetness and 100 Snowfall. And that's just one of the many things in these files.
I myself am desperately looking for the modifiers that "Wonders" do. Haven't found them yet.
