New world in Dwarf Fortess

If you want to use the tileset in fullscreen mode, locate and modify the [FULLSCREENX:800], [FULLSCREENY:600], and [FULLFONT:curses_800x600.bmp] configuration lines to match the specifications from the tileset list. The FULLFONT directive should match the filename of the tileset you downloaded. If you want to use the tileset in windowed mode, search for the [WINDOWEDX:640], [WINDOWEDY:300], and [FONT:curses_640x300.bmp] lines instead, and change them to the correct values.

The 800 and 600 values are dependent on the size of your new graphics and the size of your screen. A tileset with 16x16 tiles will be 256x256 pixels large, and the target resolution will be 1280x400, unless you change the tile width and tile height in the same file.

Slaves to Armok II: Dwarf Fortress is a single player, tile based, real time strategy, city building, and adventure game by Bay 12 Games developer Tarn Adams. The game is playable on PC, under Windows (XP+), Mac (OSX), and Linux (Most distros, contains a text only mode). Most game content is procedurally generated and the game is highly moddable. One unique feature is the continuity of the world you play in. You can play many games of fortress and/or adventure mode in the same world, each building up it's history.

It features three modes:

• Fortress Mode (real time strategy, city building)
• Adventure Mode (adventure/roguelike)
• Legends (read only view of generated history)

So to answer your question about genre, it doesn't fit into any one genre.
