What's your timeline order for the Sonic games? Here's mine:

I know many put Sonic CD before Sonic the Hedgehog 2 because of the absence of Tails, but he was mostly absent in Sonic & Knuckles as well, and isn't with Sonic all the time. Sonic the Hedgehog 4 is set before Sonic CD, since it's Metal Sonic's "grand introduction", and it's set after Sonic & Knuckles because the Death Egg has been destroyed and Eggman's revisiting his past creations.
 * 1) Sonic the Hedgehog
 * 2) Sonic the Hedgehog 2
 * 3) Sonic the Hedgehog 3
 * 4) Sonic & Knuckles
 * 5) Sonic the Hedgehog 4 Episode I
 * 6) Sonic CD
 * 7) Sonic the Hedgehog 4 Episode II
 * 8) SegaSonic the Hedgehog
 * 9) Tails Adventure
 * 10) Knuckles' Chaotix
 * 11) Sonic Chaos
 * 12) Sonic Triple Trouble
 * 13) Sonic Labyrinth
 * 14) Sonic the Fighters
 * 15) Sonic 3D Blast
 * 16) Sonic R
 * 17) Sonic Adventure
 * 18) Sonic Adventure 2
 * 19) Sonic Advance
 * 20) Sonic Advance 2
 * 21) Sonic Advance 3
 * 22) Sonic Heroes
 * 23) Shadow the Hedgehog
 * 24) Sonic Riders
 * 25) Sonic Riders: Zero Gravity
 * 26) Sonic Free Riders
 * 27) Sonic Rush
 * 28) Sonic Rush Adventure
 * 29) Sonic the Hedgehog (2006), of course where it would be placed, but then its events got erased, except for Solaris's death as a flame and the final scene
 * 30) Sonic Rivals
 * 31) Sonic Rivals 2
 * 32) Sonic Unleashed
 * 33) Sonic Colors
 * 34) Sonic Generations
 * 35) Sonic Lost World

Sonic Advance and Sonic Riders could of course fit in basically anywhere after Sonic Adventure 2 and Shadow the Hedgehog, respectively, I chose to put Sonic Riders before Sonic Rush because after both Rushes, there's Blaze's next story in Sonic 06, which gets erased, then Silver canonically meets Sonic for the first time in Rivals, then Rivals 2, which concludes the Eggman Nega arc, then go into the later games whose chronology is perfectly obvious starting from Unleashed

Might be missing a few, when researching the series I first had to list every mainstream game and I used the Sonic page for this (I so happened to read on Tails's page that he had one so I placed him right before, or even at the same time as, Knuckles' Chaotix), and it says "right after his last adventure with Sonic" so I decided that "last adventure" would be Sonic 4 Episode II)

Also not counting any games exclusive to the parallel "DS timeline" (as DS versions of games like Colors and Lost World are different, and I say the alternate version of Unleashed from the one I play (Wii) is in that timeline
