My stats (worst to best) : money, dirt, grass, wood, stone, iron, gold, ice, snow, snowflake, glacier. Money buys dirt, dirt doubles money, grass doubles dirt, wood doubles dirt and gives x2.5 grass, stone triples wood and gives 3.5x grass, iron doubles stone and gives 2.25x dirt, gold gives 1.75x iron and 1.5x wood, ice gives double gold and gives 1.8x grass, snow gives 1.8x ice and 1.5x iron, snowflake gives 1.8x snow and 1.5x stone, and glacier gives 1.6x snowflake, and 1.55x gold. And runes give boosts, but there is too many for me to say.
