Sonic games I would like to play that I've never played before.

This will be ultra brief.

Sonic Rush Adventure - I like the artwork (not so much the 3D artwork), the characters, and the rush gameplay does interest me.  Blaze The Cat kind of interests me.  Currently, I own no handheld system, so who knows when this will occur.

Sonic Colors (DS) - From what I've seen, the story isn't... all that memorable.  Again, gameplay curiosity.

Sonic The Hedgehog (2006) - This is seriously up in the air right now.

Sonic Pocket Adventure - My pleasure button could possibly be pressed very firmly with this title.

Sonic Generations (3DS) - I'm actually kind of pessimistic about this title.  It couldn't possibly be as bad as Sonic 4.
