So I'm making a large-scale strategy game, and one of the things I'm trying to do is generate a realistic-ish looking world. It turns out, this is harder than it looks. I really like the looks of the world in DF, so I was hoping maybe Toady or someone could share some insights as to how his algorithm works.

[_DivideByZero_]

Step One: Generate DF world
Step Two: Draw DF world on paper
Step Three:
Step Four: Profit!

Step one: Get two worlds.
Step two: Provide copious amounts of alcohol.
Step three: Leave them alone.
Step four: Wait.

There was that DF Talk segment where Toady discussed how the worlds were generated. Can't find it though.

Step one: Get two worlds.
Step two: Provide copious amounts of alcohol.
Step three: Leave them alone.
Step four: Wait.

Step five: Sell the recordings for additional profit or use them as blackmail against one of the worlds.

[Urist Imiknorris]

Step five: Sell the recordings for additional profit or use them as blackmail against all three of the worlds.

Fixed that for you. Why limit yourself to one when you can blackmail both worlds and their spawn as well?

Touche. Nice touch.

how is wurld formed?

To give a serious answer: Toady went on at length about the worldgen details in this Gamasutra interview (it's on page 7).

To summarize: the fractal terrain is created with 2-dimensional midpoint displacement. It seems like a pretty detailed process after that, creating biomes based on elevation, temperature, and water drainage. There are lots of online resources for fractal terrain generation online, you might want to look some of those up too.

Hope that helps. Good luck!

So using this in a Exalted game. So hard.
