Solo se necesita un sueño para crear un nuevo mundo. Unity te ofrece las herramientas necesarias para convertir ese sueño en realidad. Aquí encontrarás muchos consejos para comenzar a crear tu primer videojuego. No importa qué tantas habilidades o experiencia previa tengas: ¡lo importante es que tengas la motivación para crear algo extraordinario! 

Unity es la plataforma de creación de juegos más utilizada del mundo: el 50 % de los juegos móviles se crean con esta plataforma, el 60 % del contenido de realidad aumentada y realidad virtual está impulsado por Unity. Además, el «desarrollador Unity» ocupa el puesto número 7 en la lista de los empleos de más rápido crecimiento, según un informe reciente de LinkedIn sobre nuevos empleos en los Estados Unidos.

Comienza a crear con un microjuego listo para utilizarse en Unity. Cada microjuego incluye su propia colección de mods, los cuales son personalizaciones sencillas y divertidas que también funcionan como introducción al diseño de juegos, la lógica, los elementos visuales y más.

Los nuevos creadores pueden descargar Unity de forma gratuita y comenzar a trabajar con los microjuegos y mods listos para utilizarse en Unity. Aprende con cientos de tutoriales, cursos, términos y kits de juego gratuitos y económicos, creados por Unity y por nuestra fabulosa comunidad.
