El mundo de 2026 es un sistema complejo, conectado y volátil. Aquí no hay misiones prefabricadas ni objetivos impuestos. Eres una entidad en este mundo real: tus decisiones financieras, tus interacciones sociales y tus posibles habilidades extraordinarias tendrán consecuencias tangibles. Los personajes que encuentres son humanos con prejuicios, miedos y agendas propias. La IA actúa como el observador y el reactor, pero nunca tomará decisiones por ti. El poder está en tus manos. ¿Qué harás con él?
