I was thinking about how to make elven gameplay unique, and yet retaining the diversity of dwarf fortress.
My idea is this: instead of digging a mine, you are growing a huge-ass tree. You designate a central trunk, branches extending from it, and perhaps various other things like "flowers", "fruits" etc that may have special attributes. The difference between this and a tree-shaped dwarven megaproject is that a tree isn`t built, it grows. So when you want it higher you designate the
base level of your trunk, and then the entire structure moves 1 z-level up and stands on the new base.
How do you retain the random diversity of stones and ores found DF? By having many different kinds of branches that can grow on your uber-tree. You design the shape of the branches, using your elven woodoo, but what type will grow is up to the gods. So you randomly get all kinds of woods, leaves and fruits that you use for creating stuff.
It gets
much more complicated better. The middle of the trunk is a
Stele, a vascular tissue that transports water (
Xylem) and nutrients (
Phloem) up your uber-tree. You need to design them both. The higher and bigger your tree gets, the more
transpirational pull you need. Transpirational pull is created by water evaporating from leaves, so you will need more leaves - and more water. If you are in a dry climate, you will need to grow roots in search of water deep underground. And if you fail, parts of your tree will dry, wither and break off. And since it begins with the higher branches, they will fall on the lower, still functioning branches, creating much fun for you and your treehuggers.
The way your uber-tree grows also depends on the environment. Things like wind speed and direction, temperature, day length, light exposure, atmosphere pressure and geology will all influence the way your tree grows, so you have to consider them when you design.
You create various rooms and tunnels by "mining" inside your tree. This way you can also create hollow roots, to breach and colonize the Caverns for the glory of the elfs. Then you can grow the roots even deeper and discover why dwarves don`t live forever...
