The Patently False Pack contains my personal favourite mods for automating, building, exploring and having fun!
Ambience & Exploration
Add new sound effects & improved audio physics
Extend the available biomes, dungeons, mobs & structures
Hostile mobs are able to see players from a greater distance, adding extra excitement in dark places
Dropped items have "real" physics, instead of floating in the air
New tools, weapons, armor & curios give you a variety of ways to stay alive & accomplish your goals
Automation & Tech
Automate processes in unique ways
Develop a rocket ship & fly into space
Building
New blocks & furniture massively extend the possibilities for builds
Use elevators, portals, waystones & wormholes to spice up your travel
Fun

Play with powerful artifacts
Shrink down to a fraction of a block in height

Magic / ProjectE

EMC points are used for item exchange & storage
Quality of Life

Configuration improvements make updating mods & settings more convenient
Informational mods extend what's visible in the HUD & item tool-tips
A full-screen map, mini-map & waypoint system make it easier to explore & mark locations of interest
