People spawn radomly in front of their houses to discover their world ... chop the trees. When they meet one from the other side they'll fight each other and finally reach their houses in order to destroy them, too :P

houses give 100 exp.
inhabbitants will inherit half of their exp-points
during fight, one hit (one act cycle) does att + att * exp / 100 damage (att = 10) to the
1000 livepoints of a man,
