Building engine for ores, metals, woods, sands, gravels, other plants, ...
stone->cobble->gravel->sand-> dust | thinking: ergo specific sand color? Why is sand yellow?
Googling + Fe and washing(red -> yellow -> grey) is the answer
finding a table of the most common minerals
googling for the first, the second and the tables getting longer and longer
should I've choosen geography? I fear that wouldn't have helped me much... It seems I am going to make it to general... don't I? Would be great btw ;D - thought I can't make the game to hard because nobody would play it otherwise
