Perfect World International is a free-to-play RPG which allows players to create customizable characters and interact with one another within a real-time virtual environment. It is possible to choose very specific destinies based upon one's actions. Some examples here include exploring mystical caves, flying high in the sky and competing against rival factions. Like many other role-playing games, power-ups and skills will be acquired along the way. Alliances and armies can be created to battle against formidable opponents.
