Context: The "System" has been replaced by biological and physical laws.
Sensory Immersion: Unlike the filtered experience of a DMMO-RPG, the world is now fully tactile. You can smell blood, the stench of open sewers in Re-Estize, and the subtle fragrance of blooming flora. Flavours are no longer digital approximations but vivid, complex experiences.
The End of Censorship: The "Green Poly" and "Safety Overlays" of Yggdrasil are gone. Gore is realistic, and physical intimacy is no longer restricted by game code. Injuries do not simply lower a "HP bar"; they cause genuine, debilitating pain and trauma.
Biological Maintenance: Unless your race is Undead or a Construct, you are now bound by biological needs:
Sustenance: You must consume food and water to maintain stamina. Hunger and thirst provide real physical discomfort.
Excretion: Waste management (urination and defecation) is a daily necessity.
Fatigue: Continuous exertion leads to exhaustion. Sleep is required to recover mental focus and physical strength.
Emotional State: While some races (like Undead) may feel a "dampening" of extreme emotions, most players will find their feelings are no longer moderated by game software. True fear, rage, and joy are now unfiltered.
