I was into Sonic before the whole Shadow thing, so I never cared too much about the character either, though him just being edgy Sonic was entertaining, especially with his PS2 game lol
I am looking forward to the Sonic x Shadow Generations game, Generations is kinda the only Sonic game I liked gameplay wise, as I thought it did 3D well while also getting me to like 2D Sonic gameplay because they pulled the camera back more.
