From the referring site: 'Each player takes on the identity of a racing driver chosen to personal taste from the members of the three clans that populate the Exalight universe. A highly sophisticated customization system means that each player's avatar gets a unique appearance. Players' experience, talent and skills increase as familiarity with the Exalight universe builds up, and as more races are run. The very challenging racetracks require drivers to show tactical intelligence, making perceptive use of special powers and, above all, outsmarting the traps laid for them and the manoeuvres of rival runners.'
