Challenges

Besides the game course achievements, the gamer can live acording to self imposed limitations or goals that bring extra difficulty. These limitations can follow some imaginative scenario or some other arbitrary, fun or ridiculous ideas.

Some examples:
 * You are a kung-fu aprentice in your way to enlightment. You only need your fists and feet to fight opponents. You don't use any weapons.
 * Live as hippie and never eat meat or kill the furry friendly bears and other friends of nature
 * Live as | level 5 vegan, you never eat (or kill) anything that casts a shadow, that includes trees. Do raspberries have a shadow?
 * Some people do eat roadkill and enjoy it. Only feed on badgers, squirrels and rats.
 * Become Magellan on a raft, travel back and forth on the ocean.
 * Living as a dog, without tools, no clothes, no trading, no climbing and afraid of humans.
 * Only walking in one direction for the whole game, not turning arround or going backwards no matter what.
 * You are a caveman just unfreeze. Find a cave, the club is your only tool. Hit women on their heads.
 * Man are not welcomed to the new feminist world order. Found the feminist utopia, build a cottage and hire women to follow you. Raid places and kill the exploiting chauvinists freeing the opressed women. What to do about boys?
 * Children live in such a innocent world. Try playing with them. Throw things at each other, build rock castles, play with staffs as if they were swords.
 * The spirits gave you a vision, if you walk only backwards and always turn your back (literally) to your enemies, even if you die the spirits will guide you the secret Finish heaven.
 * You are Bear Grylls, you have your camera (you can make one with a block of wood, coz you know how) and your tools. Go someplace isolated and live without any human contact so everyone else knows you are hardcore.
 * Axes are evil. Knifes are sharp. Abolish the axe dictatorship and never use them. Try knifes instead.
 * Fire shines, Set everything you can on fire. Make huge bonfires, maybe whole villages filled with logs.
