The Realm of Innocence, unlike those games where one could randomly mix mismatched materials and easily produce potions, bandages, gemstones, gold coins, and all sorts of weapons, required that actions such as engineering, alchemy, forging, tailoring, and cooking all adhere to the basic logical principles of the world view; it would never adhere to that "conventional situation" where a bunch of messy items could be thrown together according to a blueprint conceived by a programmer in ten seconds, mashed up randomly, and yield a product.
Although this kind of realism greatly reduced the gaming experience and frustrated many who wanted to prosper and reach the pinnacle of life as lifestyle gamers, to some extent, it offered certain benefits to oddballs and professionals.
