Pues si, parece que lanzarán el juego en ambas plataformas (y quizas en Steam):

Buena noticia. Es uno de mis Sonics 3D favorito.

Juegazo, y mejor banda sonora.

A ver a que precio lo ponen...

Yahoooo

Y como ya han comentado la Bso es brutal.., a mi me encantaba White jungle

J-U-E-G-A-Z-O

Espero que la conversión sea mejor que la del Sonic Adventure, eso sí

La noticia es excelente pero me gustaría que algún día se decidieran a hacer un remake del 1º y no la versión que nos dieron hace tiempo.
