User blog:Rainbowroad6w/An unreleased skateboarding Sonic game intended to be for XBox?

An unreleased skateboarding game was intended to be for the XBox which was probably being developed between the Sonic Adventure 2 and Sonic Heroes era (probably somewhere like 2002 or 2003). Just check this blog post from Sonic Retro and just read and watch everything. This is pretty cool.
