Krysis
Once there was a time of luxury and extravagance. People got immensely decadent and only showed interest in war on weekdays and virtual adventures in fantasy worlds on the weekends. The gargantuan Multis became the new rulers of the world leading and manipulating the consumer society. The border between the real and the fantasy worlds started to diminish. The economy was clearly on the wrong track and created a civilization shaky grounds, a world full of chaos and panic -- the old values were all gone. After all the resources had been exhausted, magic was mortgaged and technical developments were forgotten. The people of the real and the fantasy worlds struggled to survive in caves. A new generation appeared, whose members inherited all the bad features of their ancestors. Now there's a new fashion gaining ground: everyone collects relics from the past.
