So these are pretty much the only Sonic games I haven't played through:

>Heroes, Shadow, 2006
>Secret Rings, Black Knight
>Lost World
>Post-Wii-Unleashed Dimps
>any racing game other than R
>all 8-bit games
>Rivals 1/2, Chronicles, Shuffle, Boom games, all the arcade/educational bullshit, the popcorn maker

Am I missing out on anything significant? I know I should play P-06 at least I just haven't gotten to it yet.
