TerraFirmaCraft Mod was initially to make the world a more realistic place. At first this just meant making the geography more realistic, but as time went on, it became apparent that terrain features were not enough to make survival mode feel right. Many others had tried to change things by making new monsters and realms, but it never felt like they addressed the core problem with Survival mode.
The world generation is very different from vanilla Minecraft, featuring a wide variety of biomes, stone layers, and vegetation. This mod is designed to make Minecraft survival more challenging and complex, while still being fun to play.
