Epic Terrain is an add-on for Minecraft 1.16 that will overhaul the generation of your Minecraft world to make it similar to the Amplified generation option for Java and Legacy Console editions of Minecraft. In addition to this, Epic Terrain adds a whole-new biome that features the pillar-like mountains found in certain parts of China. Above is a video showcasing what average terrain will look like with this addon installed!
Below are screenshots of what the average terrain of your world will look like with this.

This add-on is intended for higher-end devices and may run slowly on slower devices such as mobile platforms.
Also, It is recommended that you start a new world for this add-on as there will be strange terrain at chunk borders if you don't. These effects are pictured below. They aren't too bad, but this is just a heads-up.
