exploration - searching for materials and new metal deposits that are distributed in different biomes and in several dimensions
progress system - acquire new materials Learn to craft new tools and use them to make technology multiply your materials - from the stone age, bronze, kinetic force, steel to the NASA system to explore space
adventure - visit new dimensions Nether, End, Moon, Mars, Venus  -  in which you will only find new metals and materials
medicine - use the plants you come across to create healing recipes
vegetation -  plant vegetation lasts from spring to late summer. only one or two harvests a year. Build greenhouses and winterize so you have access to food all year round. Plants need to be fertilized and nurtured properly
