I would love to see a category with all the mainline Sonic games. The only problem is how we define what's mainline and what isn't. These are the games I would consider mainline: -Sonic 1

-Sonic 2

-Sonic CD

-Sonic 3

-Sonic & Knuckles

-Sonic Adventure

-Sonic Adventure 2

-Sonic Heroes

-Shadow the Hedgehog ???

-Sonic 2006 ???

-Sonic and the Secret Rings ???

-Sonic Unleashed

-Sonic and the Black Knight ???

-Sonic Colors

-Sonic Generations

-Sonic Lost World

-Sonic Mania

-Sonic Forces
